The "Misery" singer and her family celebrated the special occasion with cake, rollercoasters and 3-D glasses!
Gwen Stefani is toasting to five decades of love!
The "Misery" singer's parents, Patti and Dennis Stefani, celebrated their 50th wedding anniversary on Saturday at Knott's Berry Farm in Buena Park, California, with their family by their side. In typical fashion, Stefani documented the fun outing -- rollercoasters and all! -- via Snapchat.

"Congrats 50 years married!!!!" the 46-year-old No Doubt frontwoman wrote over a picture of her and her parents.
Also along for the adventures were Stefani's three children, Kingston, 10, Zuma, 7, and Apollo, 2, whom she shares with ex-husband Gavin Rossdale. Zuma was all smiles as he went on a water ride with his mom, who was rocking her signature red lipstick and a pulled-back ponytail.

Zuma proved he was totally fearless on a rollercoaster, throwing both of his hands up in the air, so as to say, "Look ma, no hands!" He was adorably concerned for his mother, however, yelling to her, "Don't lose your phone!"
While Zuma was a big fan of the park's rides, Apollo preferred meeting characters like Snoopy.

Stefani's younger sister, Jill, held Apollo while their kids snapped a photo with the life-sized beagle. It looks like a few of them even took home souvenirs!
Apollo also looked pretty rad while rocking 3-D glasses and a binkie.
Earlier in the day, the family took a break to indulge in a celebratory anniversary cake, which was decorated with white roses, gold beads and a wedding bells cake topper.
"M+D," Stefani captioned it (short for mom and dad, of course!), drawing a pink heart around the four-tiered treat.

But the sweetest of all her snaps was a pic of her parent's mid-lip lock. "Mom Dad 50 years," she captioned it, this time opting for the red drawing tool.
This is what true love looks like!
Stefani is currently gearing up to hit the road for her This Is What the Truth Feels Like tour, which kicks off July 12 in Mansfield, Massachusetts. On Friday, the rocker gave fans a peek at one her high-fashion looks, which features a giant red headpiece and a sheer floral top.

"Prepping for tour!!!" she wrote. "Can't believe it starts next month."
If the outfits we saw in her "Misery" music video -- which you can see in the video below -- are any indication of what she'll be donning onstage, we have no doubt she'll look fierce and fabulous.
