Ashton Kutcher Punk'd by 'tramp'

A man posing as a tramp has accused Ashton Kutcher of mugging him.

While in London with his wife Demi Moore for the premiere of Flawless, the actor fell victim to a practical joker.

According to the Daily Star, a man approached Kutcher in Covent Garden and asked him for money. When the actor produced a £10 note, the stranger shouted that he was being mugged.

As the man walked away he told Kutcher "you've been Punk'd" in reference to the Hollywood star's MTV prank show.
