Katy Perry brought together some of her closest friends in the music industry and her biggest fans all for a good cause. She hosted the We Can Survive charity concert last night at the Hollywood Bowl in LA and it was all about girl power, being strong and having an all-around good time!
Her pals Ellie Goulding, Tegan and Sara, Sara Bareilles, Kacey Musgraves and Bonnie McKee all participated in the show, which benefited victims of chance. Our favorite part? Their epic performance of “Roar!”
Watch their performance and find out details on Katy's upcoming tour after the jump!
