ET caught up with Kristin Cavallari, Whitney Port, and more favorites from the MTV reality show.
Looking back a decade later, would the cast of The Hills do it all again?
"I didn't realize at the time that it's essentially this soap opera," Kristin Cavallari reflected to ET. "It was just a wild crazy time, but it was fun. I mean it was a really fun time in my life."
The first episode of MTV's beloved reality show premiered on May 31, 2006, and in honor of The Hills' 10-year anniversary, ET has been celebrating "Hills Week" and catching up with the show's cast. As for signing on again, Kristin's co-stars, Heidi Montag and Spencer Pratt, were much more certain.
"I absolutely would to The Hills all over again," Heidi said, as Spencer chimed in, "I would do it so much better."
So, is the rest still...unwritten? Here's how the cast's lives have changed 10 years after The Hills.
Lauren Conrad
Lauren left The Hills drama behind and married lawyer William Tell in a rustic-chic ceremony in 2014. She has turned her reality fame into a reported $25 million fashion and lifestyle empire, debuting her runway collection at New York Fashion Week last fall and publishing nine books so far.
The 30-year-old designer also confirmed her return to reality TV on her website, sharing that she would be featured in a MTV anniversary special on Aug. 2. "Looking back, I am grateful for the incredible opportunity we were given to take part in this show," she wrote along with the announcement, "the experience taught me so much and forever altered my life and my outlook for the better."
Whitney Port
Whitney's spin-off series, The City, only ran for two seasons, but it's where she met her now-husband, Tim Rosenman, who was a producer in charge of setting up her on-camera dates. The couple tied the knot in 2015.
The 31-year-old designer also has a successful streetwear line, Whitney Eve, and a lifestyle blog, WhitneyPort.com.
Everything else, Port says she's taking "day by day." "I'd love to eventually start a family and become a mom," she told ET. "Not happening in the super near future, but definitely something that I would love to be able to do."
Audrina Patridge
Audrina is currently expecting her first child, a baby girl due in July, with her fiancé, Australian BMX rider Corey Bohan. "I'm pregnant, so that is probably the biggest change for me," she told ET. "And then being engaged and planning a wedding. It's like I'm all grown up now."
Fun fact: The couple went on their first date during The Hills. "Corey was on the show for a hot second," Audrina dished. "Corey was such a good guy and I was like, 'He's so nice. It's not fair to involve him in all of this drama.'"
Heidi Montag
Heidi and husband Spencer Pratt have been living in his parents' rental property for six years and admit that finances are tight as self-proclaimed "professional reality stars." Heidi, 29, most recently appeared on Lifetime's The Mother/Daughter Experiment.
"Well, bless the British. We did Celebrity Big Brother in England and that took care of many years of not having to worry about working," Pratt explained. "You know, you just keep doing television shows. And thankfully we don't have rent to worry about."
Spencer Pratt
As for whether the couple infamously known as Speidi will ever get their own show, Pratt told ET, "It's so hard. The stakes are so much higher now. We walk dogs and eat burritos, you know. Maybe if we have a child and it's an alien."
The 32-year-old reality villain is still very much into crystals and has hundreds in his home -- which may explain why he says he no longer hates Lauren Conrad. "I don't have the energy to hate people," Pratt told ET. "I try not to have that type of energy."
Justin Bobby
Justin Bobby, once deemed "a man so great he needed two names," is actually Justin Brescia. When he left The Hills, he said he went to Nicaragua. "First, surfed my brains out, ate a lot of good food, and then I opened up a salon down there," he reflected.
Now, the 34-year-old musician lives in Austin and is focused on his alternative punk rock band, BobbyrocK -- though he still cuts hair sometimes. "Not as much as the music, but I'm a sucker for that s**t," he revealed.
Jason Wahler
Jason, the boyfriend Lauren skipped Paris for in season one, has been open about his addiction struggles since the show ended and told ET it got so bad that he attempted suicide seven years ago. "Not contemplation, actually attempting suicide," he shared. "Somebody found me and that's why I'm still here today."
The 29-year-old former reality star now runs a sober living facility called Widespread Recovery in Orange County, California. He married Ashley Slack in 2013 and the couple is hoping to expand their family soon. He told ET, "We want probably two, but I want to be in a spot where I can actually raise my kids and be a part of their life...Hopefully next year, we'll have a little junior."
Kristin Cavallari
Kristin married Chicago Bears quarterback Jay Cuter in 2013 and is mother to three: Camden, 3, Jaxon, 1, and daughter, Saylor, who was born in November. She's designed her own line of shoes and jewelry, too, and recently published a memoir, Balancing in Heels: My Journey to Health, Happiness, and Making it all Work.
Though the 29-year-old former Laguna Beach star told ET she's still close with Heidi and Audrina, she also said she would never do another reality show. "No! We get offered it all the time," she said, objecting to her family getting their own show. "We want our kids to live as normal a life as possible."
Brody Jenner
Brody kept his reality TV career alive, post-Hills, even popping up on Keeping Up With the Kardashians. Earlier this month, the 32-year-old personality popped the question and got engaged to his "lover and best friend," fianceé Kaitlynn Carter.
His famous ex, Kristin Cavallari, approves of the couple. "I love Brody, and she's so sweet," she told ET. "I'm really, really happy for them...It's such an exciting time in both of their lives and I know Linda, his mom, loves her, so she must be so excited."
