The Hangover star Bradley kept a low profile as he sat next to Mirka in the players' box on Court 1 on Wednesday (8 July), watching Roger's match against Gilles Simon.
Bradley's a friend of Roger's and has been spotted supporting him at Wimbledon in the past.
He also attend Roger's 31st birthday a couple of years ago.
Last year, we saw Oscar-nominee Bradley and his then-girlfriend Suki Waterhouse enjoying the tennis on Centre Court, while the year before that was the great Bradley Cooper / Gerard Butler bromance moment, when they were caught taking selfies together in the royal box!
Also at Wimbledon today were The Duke and Duchess of Cambridge, David Beckham and son Romeo, and actor Josh Hartnett with his pregnant girlfriend Tamsin Egerton.
