Katy and Britney met and posed for photos together on the blue carpet. Katy took her grandmother Ann Hudson to the premiere, and grandma wore a T-shirt that read: "I've got the hots for Papa Smurf." 

Britney was accompanied to the premiere her two sons Jayden James, who's 6, and Sean Preston, 7. The kids also make cameos in Britney's music video for "Ooh La La."
