Mirror, mirror, on the wall. Who's the biggest diva of them all? Plenty o' divas -- like Beyonce, Jennifer Lopez, Madonna and many more -- turned up to support and perform at Chime for Change: The Sound of Change Live, a concert held at Twickenham Stadium yesterday (June 1) in London.

Chime for Change is a global campaign, founded by Gucci, for girls' and women's empowerment. That's always a favorite cause of Queen Bey, who is on the founding committee. She rounded up so many divas we could barely keep track! Girl power!

Check out the PopCrush photo recap of the diva-studded event!
