'Ugly Dolls' premiere: Kelly Clarkson, Gwen Stefani and more stars bring their kids

Family night out!

The stars of "Ugly Dolls" stepped out for the film's premiere in Los Angeles on Saturday, and it was a star-studded family affair featuring some celebs' rarely-seen kids hitting the carpet.

Kelly Clarkson, who voices a character in the animated flick, stepped out alongside her husband, Brandon Blackstock, and their four children: daughter River Rose, 4, and son Remington, 3, in addition to Blackstock's two children from a previous relationship, daughter Savannah, 17, and son Seth, 12. The full family outing marked the first public event that Clarkson and Blackstock attended with all of their kids.

Stefani and Shelton stepped out with Kingston, 12, Zuma, 10, and Apollo, 5, and the eclectically-dressed clan was all smiles while posing for photos together.
