Are Cameron Diaz and Prince Harry gym buddies?

New celebrity friendship alert! As unlikely as it seems, Hollywood star Cameron Diaz has reportedly started sharing workout sessions at the gym with new pal, Prince Harry

New celebrity friendship alert! As unlikely as it seems, Hollywood star Cameron Diaz has reportedly started sharing workout sessions at the gym with new pal, Prince Harry.

The American A-lister - who is filming new movie Gambit here in the UK – apparently bumped into the party-loving prince at an exclusive fitness studio in London’s Kensington.

According to an eyewitness at the gym, the pair have been challenging one another to races on the treadmills - and Cameron keeps winning!

‘Producers secured her membership at the ultra-discreet, £3,500-a-year gym – totally unaware Prince Harry was also a member,’ an insider told the Daily Mirror.

They added: ‘Since first spotting one another and saying hello, they’ve coincided visits on two further occasions…They’ve become pretty friendly. Harry even invited his new gym buddy out drinking with him and his chums.’

Cameron Diaz is apparently adding extra workout sessions to her fitness schedule to get in tip-top shape for her role in Gambit, in which she plays a rodeo rider alongside Colin Firth and Alan Rickman in the new Coen brothers flick out next year.
