Hollywood superstar Brad Pitt was forced to hitch a lift from a paparazzo when his motorbike broke down on a busy Hollywood street.

The Troy star was being tailed by photographers as he rode his classic motorcycle through Los Angeles and the snappers got their shot when Pitt's vehicle came to an abrupt halt, reports said.

The 45-year-old attempted to fix the bike but when his efforts failed, he thumbed for a lift from a snapper who kindly obliged the actor.
