Gwen Stefani kicked off her parents' 50th wedding anniversary with a day of family fun.
In honor of her mom and dad's big day, the "Used to Love You" songstress and her three children—Kingston, 10, Zuma, 7, and Apollo, 2—headed to Knott's Berry Farm in Buena Park, Calif. with the happy couple, enjoying plenty of roller coaster rides while they were at it.
In one Snapchat clip, Stefani hits a ride with son Zuma, who tells her, "Don't lose your phone," before throwing up his hands as they go down a hill on the rollercoaster while Stefani shoots the action on her cell phone. In another Snap, Zuma lays back on his mom as they enjoy a more calm part of the ride.
After the duo had some action-packed bonding time, Stefani and Apollo played video games, which she also posted a shot of on Snapchat. In the sweet snap, the duo rocks matching 3-D goggles as Apollo sucks on a pacifier and his mom helps him hold a device up to the screen.
Those were just a few of many snaps Stefani posted of their day out at the amusement park, which included snaps of her mom and dad as well. "Congrats, 50 years married," Stefani wrote on one selfie that showed her posing in the middle of her smiling parents. She also posted another shot that featured her mom and dad kissing, with a heart drawn around them, and shared photos of their gold-embellished anniversary wedding cake topper as well.
