Maria Sharapova, Stanislas Wawrinka and Juan Martin del Potro hit the bustling concert scene in London last week.
Sharapova and Wawrinka attended a Rihanna show at Twickenham Stadium.
Del Potro went to Wembley Stadium with his coach to see his "idol" Bruce Springsteen.
And to top it all off, Sharapova even got a nice shout-out from Rihanna. https://twitter.com/rihanna/status/346219764454146049
