Singer Rufus Wainwright asked his friend Helena Bonham Carter to star in his new music video and he convinced the British actress to strip off for the racy promo.

The musician wanted a video to remember for his latest single Out Of The Game, and the Harry Potter star had no qualms about being filmed in her underwear.

He tells Britain's The Sun, "It features the two of us being naughty in the library. We have been friends for years. Not only is she very beautiful, very glamorous, but she is also incredibly funny.

"At the end of the video she is basically wearing a bra. So I very much appreciate her friendship for furthering my career".

In other related news Wainwright has credited his baby daughter with helping him overcome his grief following his mother's death.

The gay star was left devastated in 2010 when his mom Kate McGarrigle lost her battle with cancer.

However, just a year later, Wainwright and his partner, Jorn Weisbrodt, became parents to a little girl called Viva, whose mother is Leonard Cohen's daughter Lorca, and the singer is convinced the baby's arrival saved him from losing his sanity.

He tells Britain's The Sun, "Seriously, it's a lovely turn of events. It all coincided with my mother's death and I can

't totally vouch for my sanity at that time but I did wake up and I have this beautiful daughter to help me through. And I thank her mother very much for giving me that.

"She's adorable. She's beautiful. She walked at nine months. I know touring will be difficult being away from her as this kid is really going be the captain of my ship for a long time. She spends most of her time in L.A. or Paris and I miss her when we are apart".

Wainwright also reveals Viva is already being introduced to music. He adds, "Whether she will follow both her families into music, I don't know but she already has a very high-pitched scream... maybe she'll become an opera singer. But it's really about what she chooses to do and I'll be happy".
