Brad Pitt has splashed out £250,000 on a World War Two Nazi motorbike.

The 51-year-old star - who became obsessed with wartime relics after starring in 'Fury' - has splurged on a 1942 three-wheeled vehicle that was used by a German reconnaissance unit and was used to travel across mountains and across deserts in Crete.

The bike was sold by Nazis in 1945 at a local auction and later ended up in the hands of an Athenian bike collector named Yannis, who is now selling the ''collectors piece'' to the Hollywood hunk.

Yannis told the Daily Mirror newspaper: ''There are only around 500 of these bikes worldwide so they are collectors pieces like paintings and go up in value all the time

''It's a way for wealthy people to invest their money and also enjoy their hobby.

''Even the parts are expensive if they are original. I had to replace a small piece of metal on this bike and it cost me £1500.''

It's not the first time the 'Fight Club' actor - who raises six children with wife Angelina Jolie - has purchased pricey rides; he already owns around 10 different bikes and even bought eldest son Maddox,14, a Suzuki DRZ-125 for his 11th birthday as he wants his kids to enjoy biking around their home.
