Blake Shelton and Kelly Clarkson turned the L.A. premiere of UglyDollys on April 27 into a family friendly event.

Blake was in attendance with his girlfriend Gwen Stefani and her three kids—Kingston Rossdale, Apollo Rossdale and Zuma Rossdale—while Kelly was in tow with husband Brandon Blackstock, children River Rose and Remy, and step-children Savannah and Seth.

Blake and Kelly voice animated charters in the UglyDolls movie, which is based on the UglyDolls toy brand that features “characters who are distinct for their endearing ‘ugliness’ in a wonderful ‘uglyverse’ where differences are celebrated and embraced.”

According to the movie’s press release, “Unconventionality rules in UglyDolls, the new animated family adventure based on the beloved toy brand. In the adorably different town of Uglyville, the free-spirited Moxy and her friends confront what it means to be different, struggle with their desire to be loved, and ultimately discover that you don’t have to be perfect to be amazing because who you truly are is what matters most.”

Blake’s character, Ox, fancies himself the defacto mayor of the UglyDolls, while Kelly voices Moxy, the confident leader of the group.

STXfilms will release UglyDolls in theaters May 10. An animated kids series is also underway with a full series order from Hulu.
