'Tis the season for love!

Although we've seen a fair amount of breakups this year (Anna Faris and Chris Pratt, Fergie and Josh Duhamel, Ben Higgins and Lauren Bushnell, just to name a few), there are plenty of couples that were still able to restore our faith in romance in 2017.

Now, ET's breaking down the most adorable celebrity couples that are still going strong!

2018 will be an exciting year for the lovebirds, who are currently planning their royal spring wedding at St. George’s Chapel in Windsor Castle, England. After dating since May 2016, the two officially announced their engagement in November.

"The fact that I fell in love with Meghan so incredibly quickly was a confirmation to me that all the stars were aligned and everything was just perfect," the royal gushed during his first post-engagement interview with Markle. "I know the fact that she will be really unbelievably good at the job part of it as well is honestly a huge relief to me because she will be able to deal with everything that comes with it."

"We are a fantastic team," he added. "We know that we are, and we want to, over time, have as much impact for all of the things that we care about as much as possible."

This was a romance we didn't see coming, but we love it! J.Lo and A-Rod shocked the world when they were spotted hanging out together in February. It wasn't long before the two made it official, confirming their relationship in multiple interviews, and they have been seemingly inseparable ever since. From date nights in Miami to relaxing getaways in the Bahamas, the two have showed plenty of PDA this year, all over the world.

Plus, their kids seem to adore each other. Lopez's 9-year-old twins, Emme and Maximilian, have shared plenty of play dates with Rodriguez's daughters, Natasha, 13, and Ella, 9.

"I understand him in a way that I don't think anyone else could, and he understands me in a way that no one else could ever," Lopez said of her relationship with the former MLB star in an interview with Vanity Fair. "In his 20s, he came into big success with the biggest baseball contract [at the time]. I had a No. 1 movie and a No. 1 album and made history. We both had ups and downs and challenges in our 30s, and by our 40s we'd both been through so much. And more importantly than anything, we had both done a lot of work on ourselves. We had to grow and discover ourselves first."

John Legend and Chrissy Teigen

These two topped our list last year, and we couldn't help ourselves from including them again! The hilarious duo celebrated their fourth wedding anniversary this year with a seriously sexy date night. Two months later, Teigen and Legend revealed in an Instagram video that they are expecting their second child together through in vitro fertilization.

"Luna, what's in here?" Teigen asked her 1-year-old daughter, Luna, who replied, "Baby!" while rubbing her mama's belly.

"Chrissy and John are so excited to be having another baby -- and Luna is too!" a source told ET at the time. "They are incredibly grateful to be adding to their family."

Khloe Kardashian and Tristan Thompson

It was revealed during an episode of Keeping Up With the Kardashians that the reality star actually met the NBA player on a blind date. Romance rumors ignited last September when the two were spotted packing on the PDA in Miami. Since then, they haven't been shy about their relationship, kissing in public and tagging each other in posts on social media.

And the two have recently taken their love to the next level! In October, a source told ET that Kardashian and Thompson are expecting a baby boy together, one month after we confirmed the Revenge Body star was pregnant.

"We love Tristan so much, and she's so happy, and she's been through so much," Kris Jenner said of her daughter during an interview with ET in October. "To be in such a great place in her personal life is amazing. She's really happy."

Justin Bieber and Selena Gomez

Jelena forever! Shortly after calling it quits from The Weeknd in October, Gomez was spotted spending time with her on-again, off-again ex-boyfriend, Justin Bieber. Since then, the two have been photographed riding bikes together, attending church services, cozying up during an intimate date night in Los Angeles and packing on the PDA.

The "Wolves" singer recently opened up about reigniting the fire with Bieber in her interview with Billboard magazine. "I'm 25. I'm not 18, or 19, or 20," she explained. "I cherish people who have really impacted my life. So maybe before, it could have been forcing something that wasn't right. But that doesn't mean caring for someone ever goes away."

Blake Shelton and Gwen Stefani

These two make it feel like Christmas! Yep, the country crooner and No Doubt rocker are still going strong after passing their two-year mark as a couple in November.

While Stefani's three boys, Kingston, 11, Zuma, 9, and Apollo, 3, have seemingly been big fans of Shelton since the beginning, he's spent a lot more time with them in 2017, including trips to Disneyland and his home state of Oklahoma, and featuring them in his "I'll Name the Dogs" music video. A source close to the couple told ET in October that Shelton is hoping for a few kids of his own… with Stefani, of course

"Gwen would love nothing more than to give Blake his first child," the source said. "Blake is dying to be a father. He loves Gwen's kids, [which has] made him realize he could be a good father."

The American Horror Story: Cult star had us all in tears when he shared a video from his October wedding to YouTube.

"This video makes me cry every single time I watch it," he captioned it. "It was the most special day of my life and we wanted to share a little bit of it with y'all."

Haynes and Leatham said "I do" in a beautiful, white-themed ceremony officiated by Kris Jenner in Palm Springs, California. They got engaged in March, one month after confirming their relationship via Instagram.

The hip-hop world couldn't keep their cool when they discovered the "Bodak Yellow" singer and Migos rapper, who reportedly first locked eyes in February, reignited their romance in October following a brief breakup. In one of the most exciting onstage moments of 2017, Offset adorably proposed to Cardi B while the two were performing together at Power 99's Powerhouse in Philadelphia, Pennsylvania, in October.

"Jesus Christ I'm so emotional, @offsetyrn I loveee you so much," Cardi B wrote on Instagram, with a photo of her massive sparkler. "Thank you for seeing the potential in me since you met me. For giving me advice molding me and loving me. You're such a amazing man to me your family, friends, kids and you are extremely talented. I can’t wait to spend FOREVAAAA with you. Lets make a lot shmoney and love together."

Who doesn't love a good Dancing With the Stars love story? The professional dancers -- who dated in 2016 but briefly called it quits -- reignited their romance in June, making it official by sharing pics of each other during a romantic European vacation.

Since getting back together, the adorable duo has been posting plenty of PDA-filled pics via social media, but nothing has warmed our hearts more than the time they shared the stage for a performance during DWTS' season 25 finale.

"I'm in a great place and I'm in love," Chmerkovskiy told The Insider in August. "I'm very grateful for that."

It's been an amazing 2017 for this power couple, who welcomed their first child together, daughter Sienna, in April.

"Real life is awesome," the singer gushed to ET at the 2017 Billboard Women in Music event in November. "I have to say, I'm just very grateful for the special love that we have. He's awesome. He's amazing."

Ciara, who is also mother to 3-year-old son Future, said "I do" to the NFL pro last July in Cheshire, England. It's seemingly been a fairy tale romance since day one for these lovebirds!

Ciara is also "so happy" for her BFF, Serena Williams, who wed Alexis Ohanian in November. The two tied the knot in a stunning, Beauty and the Beast-themed ceremony in New Orleans, Louisiana, surrounded by their closest family and friends. The tennis pro later said she "felt like a princess" on her special day thanks to the dress advice she received from Vogue editor-in-chief Anna Wintour.

"The crowd was roaring," a source told ET at the time. "Everyone had a blast."

The wedding came just two months after Williams and Ohanian welcomed their first child together, daughter Alexis.

The professional dancer took a break from judging Dancing With the Stars' 25th season after tying the knot to the NHL pro in July. Although the pics from their intimate ceremony near Coeur d’Alene, Idaho, were breathtaking, we think it's safe to say their honeymoon pics were even better!

From workouts on the beach to sexy snaps on the rocks, no one does honeymooning like Mr. and Mrs. Laich!

ET recently spoke with Hough at Disney World, where she revealed how she and Laich plan to spend their first Christmas as a married couple.

"I think we're just honestly just going to be home together," she explained. "We've always said that, between the two families, we'll always have a year in between for ourselves. 2017 was incredible. Getting married to the love of my life was the best thing ever. It's going to be hard to top. But it's all about moving forward and embracing what is next."

It's been an exciting 2017 for the Orange Is the New Black star, who married show writer Lauren Morelli in Palm Springs, California, in March, less than a year after announcing their engagement.

"It's great," Wiley said of married life while speaking to ET at Television Academy's pre-Emmys party in September. "We fell in love and the love is real, and we're still so happy. I wouldn't be able to be here without her support. My professional journey really started with Lauren, working side by side, and now having her in the role that she is, being my wonderful wife, she's helped me through every single stage."

Although these two have yet to confirm their relationship on their own, we can't get enough of how head over heels these Stranger Things co-stars seem to be for each other, since sparking romance rumors in January. The two were most recently spotted in November, sharing a steamy smooch in London, England, just a few days after holding hands in Paris, France.

But seriously, can you guys just admit you're in love already? Because it's turning our world Upside Down! #TeamJonathan

Life is pretty great when you're dating a superhero… just ask Jenny Slate!

Fans were beyond excited when the Parks and Recreation actress and Captain America: Civil War star began dating in May 2016, and devastated when they briefly broke up in January of this year. But all is well now -- the two are officially back together!

Slate teased their reconciliation via Twitter in early November, writing, "My boyfriend does many dreamy & generous things but number 1 in my mind right now is how he celebrates my new turtlenecks/let’s me show him my online shopping spoils & cheers me on."

She was seemingly referencing her June 2016 interview with ET, in which she called Evans a "dream."
