Christina Milian, Nicole Scherzinger Race to 'Cars 2' Premiere

The stars revved up for the premiere of Disney’s Cars 2 over the weekend. Christina Milian, who has been spending time in the studio lately recording her album, made it a family affair with her nephew and daughter Violet, who was preoccupied chewing on her mom’s necklace.

“X Factor” judge Nicole Scherzinger, beaming in a fuchsia gown, held hands with her boyfriend, Formula 1 driver Lewis Hamilton.

Meanwhile, Travis Barker was the coolest dad on the carpet, checking out the animated flick with his two kids at Hollywood’s El Capitan Theatre.
