'Part of Me' preems in Hollywood

The crowds sweltered on Hollywood Boulevard, but Katy Perry, in a red velvet dress and stilettos, looked pop-star perfect as she worked the pink carpet and waved to fans at the premiere of Paramount’s Insurge release “Katy Perry: Part of Me” on Tuesday evening.

“It’s somewhat nice to be a role model,” Perry told Variety, “but I can’t make decisions for others. All I can do is encourage young people to follow their dreams and not sit around waiting to win the lottery.”

Tween magnets Selena Gomez, Victoria Justice and Carly Rae Jepsen mingled with Par execs Adam Goodman and Rob Moore, Grammy topper Neil Portnow, helmers Dan Cutforth and Jane Lipsitz and producer Craig Brewer.

Outfitted in candy wrappers and film cans, Perry burst out of a giant popcorn box on the stage constructed on the closed-off boulevard and treated preemgoers and hordes of noisy Katy Cats to an eight-song set before the film.

After the screening, the hard-working singer, still not content to call it a night, marched over to engage with the scores of young admirers waiting outside.
