Hear Them Roar: Katy Perry Organizes Major Girl Power Moment

Katy Perry got together some of her gal pals and fellow amazing musicians for some serious female empowerment at the Hollywood Bowl last night. Tegan & Sara, Ellie Goulding, Bonnie McKee, Kacey Musgraves and Sara Bareilles all joined Katy, 28, at the We Can Survive: Music For Life event. Proceeds from the concert went to help fight breast cancer and the theme of the night was definitely girl power.

At the end of the night, all the ladies go on stage together to sing Katy’s single, ‘Roar’ in what I can only imagine was an “I’m every woman,” estrogen booming moment.
