Robert Pattinson has joked that he got a new haircut because he caught headlice.

The Twilight hunk, 24, was snapped out in LA on Sunday with a pretty radical trim.

‘I got a terrible infestation of nits and I had to shave it all off,' he joked during a taping of Ellen DeGeneres' US chat show.

But Robert, 24, later revealed the real reason for his new look - he had to get a specific hairstyle for his role in new movie Water For Elephants.
