Katy And Friends
Katy Perry and some of her favorite female acts performed at L.A.’s Hollywood Bowl last night (October 23) for the We Can Survive: Music For Life charity concert helping the fight against breast cancer. Perry closed out her headlining set by spreading the love with a massive rendition of “Roar” featuring Sara Bareilles, Ellie Goulding, Tegan And Sara, Kacey Musgraves and Bonnie McKee (who gets a special shout from KP for co-writing the song).

That wasn’t Perry’s only surprise of the night. Earlier in the set she brought out Juicy J for “Dark Horse.” Check out the girl-power version of “Roar” up top, and see “Dark Horse” below.
