Colin Farrell has confessed he was probably high on drugs and alcohol when he agreed to film his infamous sex session with Playboy model Nicole Narain.

The Irish star took Narain to court in a bid to try and stop the distribution of the sex tape in 2005, but now admits the footage wasn't at all bad for his career. However, he still wishes he'd been sober when Narain put the idea of a sex tape to him.

He says, "I think I was high... It seemed like a good idea at the time."

And the actor admits he fought to keep the footage off the Internet for fear of what his mother might say if she saw it: "God forbid, she'd tell me something like, 'Oh you remind me of your father at certain angles.'"
