Katy Perry surprised those attending the L.A. premiere of her tour documentary, Katy Perry: Part of Me, with a free concert outside Grauman's Chinese Theatre last night.
The singer wore a bustier fashioned to look like two reels of film and a popcorn box trimmed skirt — normal Katy Perry attire. Later, she changed into a red velvet, old Hollywood style dress with glam, 50s era waves.
She told MTV News she hopes her film is "an inspiration" for those who watch.
"When they see it, they are like, 'Oh, yeah, she goes through some sh** too,'" she said. "'I can't dodge life's curve balls if Katy Perry can't dodge life's curve balls.'"
Selena Gomez, Carly Rae Jepsen, Kathy Griffin, Victoria Justice and Rebecca Black also attended and walked the pink carpet.
