A karaoke night for porn stars has become a hit in the US.

Once a week, Sardo's Grill and Lounge in Burbank, California hosts an unusual night out - a karaoke evening for adult film stars.

Partygoer Daniel Hogan said: "It gives normal people a chance to get a little wilder than they normally would."

As well as the film stars themselves, camera crews and other's who work in the porn industry are invited along for the night.

Despite being filmed having sex for a living, porn actress Magdalene St. Michaels says singing in public is far scarier.
