Hollywood actor Tom Cruise crashed a teenage fan's dirt bike into a wall while showing off some stunts.

The 'Knight and Day' star was reportedly asked by the fan to have a go on the speedy two-wheeled vehicle outside the Scientology Celebrity Centre in Hollywood. He lost control, crashed and ended up scraping the bike all up the side, reports contactmusic.com.

He reportedly told the young fan: 'Guess I got a bit carried away. Give me your name and phone number, and I'll have it fixed good as new'.

However, the teenager decided he would rather keep the bike in damaged state, autographed by Cruise.

As he started to head home, the teenager is said to have shouted at the actor: 'Thanks for breaking my bike in!'
