Tyson did 'Hangover' to fund "drug habit"

Mike Tyson has revealed that he accepted a role in The Hangover in order to fund his "drug habit".

The former boxer appeared in the 2009 comedy as himself, singing to Phil Collins's 'In The Air Tonight'.

Tyson told Gridlock: "I was doing that to supply my drug habit… I said, 'Wow, This is going to be really good. We're going to sell this stuff on 42nd Street on bootleg and make a lot of money'.

"This is my best thinking on drugs… It wasn't that way. It was an international success."

The 44-year-old has been sober since the death of his 4-year-old last year.
