Federer attends Bruce Springsteen concert and meets 'The Boss' backstage

Roger Federer was in London for his Centre Court celebration to start the week at Wimbledon and his trip to London wasn't complete without heading to Hyde Park to see Bruce Springsteen.

Springsteen is playing two nights as part of the British Summer Time series and plays the second tonight, but Federer was in attendance (barring a time machine) seemingly on Thursday.

On his social media, the Swiss legend posted a video of the legendary singer on stage as well as a photo backstage.

Springsteen was holding a tennis racquet and posed alongside Federer.

It has been a good few weeks for concerts for Federer who also attended Coldplay in Zurich and sang on stage alongside the British band.

But he didn't join The Boss at Hyde Park to show off his talents.

Enjoying his retirement to the max though certainly.
