After celebrating her parents’ 50th anniversary with a sweet party and some cake, Gwen Stefani treated her boys to a fun day at Knott’s Berry Farm over the weekend.

The former Voice coach shared photos and videos Saturday of her adorable sons — Kingston, 10, Zuma, 7½, and Apollo, 2 — on her Snapchat account from various rides at the amusement park.

PEOPLE also has exclusive photos of the rocker and her kids — along with her niece Stella — riding the new Ghostrider ride.

“They rode Ghostrider four times and were also seen picking out candy and taffy in Camp Snoopy,” an onlooker tells PEOPLE.

The singer, 46, heads out on tour next month, but has another milestone to celebrate first — her boyfriend Blake Shelton celebrates his 40th birthday on Saturday.

“I just want my boys to be happy and healthy, and I just ask God to guide me every day to be a good mother because it is not an easy job,” she said recently about motherhood.
