Porn

Ashton Kutcher once rapped to a room full of porn stars.

The 30-year-old actor was in Las Vegas for the Annual Video and Software Conference when he had an "insane weekend" that saw him end up on stage with porn movie actor Ron Jeremy.

He explained: "I was there in Las Vegas to collect an award and found out that the adult film awards were happening the same night.

"I turned $1 000 into $25 000 playing craps, then ended up on stage with a rap group, with a bottle of champagne in one hand, standing next to Ron Jeremy, rapping to a sea of porn stars and silicone.

"The rest of the night is fuzzy."

Before marrying actress Demi Moore in 2005, Ashton was famed for his party lifestyle and was a member of P Diddy's 'Ratpack'.
