It's party time!
...for some famous celebrity kids.
Beyoncé, 34, and husband Jay-Z, 46, brought daughter Blue Ivy Carter, 4, to a friend's birthday party at the restaurant Giggles N' Hugs in Century City, Calif. on Saturday afternoon. They were joined by Kelly Rowland, 35, and son Titan, 1, as well as Ellen Pompeo, 46.
Bey wore a long sleeve black floral top, a light blue, ripped denim knee-length skirt and black platform lace-up ankle boots. She paired the look with pink glasses.
