Brad Pitt has splashed out on graffiti paintings of the British royal family.

The 'Moneyball' actor - who is currently based in the UK while partner Angelina Jolie films 'Maleficent' - bought three pieces from British artist Bambi, a canvas of Prince William and his wife Duchess Catherine, one of Queen Elizabeth and another picture of Amy Winehouse.

A source told The Sun newspaper: ''There is a lot of buzz about Bambi at the moment. As Brad's here with the family for up to two years, it makes sense to fill the house with art by British artists.

''He already has a Banksy, which he bought for £1 million at a London auction, but shipped it to LA.''

Earlier this week, Brad made a surprise visit to see Mohammed Hussain, a Birmingham-based solicitor who worked in the security team on the actor's 2000 film 'Snatch', and spent 20 minutes chatting to his pal's staff.

Mohammed said: ''He's a lovely guy, one of the most humble men you could meet.

''Brad and Angelina are in the UK for the next 18 months filming back-to-back.

''He loves Britain and he's been in Harrod's every other day shopping for the kids.

''It was a real surprise - it was out of the blue.

''The last time I saw him was in Cannes a couple of years ago.

''We don't publicise things like this. It's a Friendship thing more than anything.''
