Serena Williams and Beyoncé together? Could you possibly ask for more? The Bey of the tennis world paid homage to the Serena Williams of the music world (whatever — they're equally badass) with her own video homage to "7/11." Are there Kale sweatshirts? No, but there are leopard-print tennis outfits, and that's good enough for us. Vogue's April cover girl nails every beat in this GoPro-shot tribute. She hits the tennis courts, she hits a random hallway (so Bey!), she hits a golf course. It's like a workout DVD and music video we can't stop watching. Note to Andy Murray and Roger Federer: It's time to step it up, boys.
