Don your tennis whites with Sienna's Ralph Lauren dress

It's been a big day in the sporting world, with Andy Murray having just been crowned Wimbledon champion, and the final of the World Cup still to come later today. Of course amidst all that excitement we're loving seeing what the stylish celebs are choosing to wear for the occasion!

She told Vogue last year: 'He opened the door to a world of filmmakers I didn’t have access to before. Directors speak to each other. . . Everybody calls the last director you worked with, so it being Bennett Miller was a hugely beneficial thing.'
