GETTING ANIMATED

It's a teenage pop music dream! Britney Spears and Katy Perry join forces on the red carpet Sunday for the Westwood, Calif., premiere of The Smurfs 2. Spears brought sons Sean, 7½, and Jayden, 6½, (and beau David Lucado) as her dates, while Perry was joined by her grandmother, Ann Hudson.
