The retired boxer reveals he has become close friends with Cooper since they worked together on the hit 2009 comedy and he recently treated his pal to a unique gift straight from his trophy room - one of the belts he was awarded when he was crowned the World Boxing Council (WBC) heavyweight world champion.

Tyson asked his daughter to deliver the present by hand when she recently checked out Cooper's Broadway play The Elephant Man.

Showing off a photo of the Oscar nominee holding the belt above his head during an interview on U.S. morning show Live with Kelly and Michael on Thursday (12Mar15), Tyson explained he wanted to give the American Sniper actor something really memorable, "because he deserves it".

He added, "Look at what he's accomplished from The Hangover. Look at how far he's come..."

Tyson first won the WBC title in 1986 and retained it until he lost to Buster Douglas in 1990. He won it back in 1996.
