Charlie Sheen insists he wasn't responsible for the gunshot injury his ex-fiancee Kelly Preston suffered in 1990.

The troubled star has always been surrounded by rumours he had a part to play in the incident but he has now claimed it was Kelly - who is now married to John Travolta - who accidently fired the gun.

Speaking about what happened during his 'My Violent Torpedo of Truth/Defeat is Not An Option' live comedy show in Vancouver, Canada, he said: "I thought she was still asleep upstairs. And I heard a f**king gunshot go off. I thought, 'She did it, she finally f**king did it. She killed herself and they're going to f**king blame me.'

"I come around the corner and there's naked Kelly Preston at the top of the stairs, holding her wrist, staring at me, covered in blood ... and I thought, that's pretty f**king hot ... I didn't, I didn't."

Charlie claims Kelly picked up a pair of his trousers which contained a small firearm and set it off by mistake in their bathroom causing a bullet to possibly hit the toilet leaving her injured by the Ricochet or a piece of shrapnel.
