Ke$ha willing to have sex with Justin Bieber

Ke$ha has revealed she would like to have sex with Justin Bieber.

The "Die Young" singer - who is known for her controversial style - has admitted she would definitely consider bedding the 18-year-old "Boyfriend" singer now that he is legal.

Asked whether she would consider having sex with the Canadian heartthrob, the 25-year-old singer told Rolling Stone magazine: "Sure. Wait, is he even legal? Could I go to jail for this?"

Once informed that the singer celebrated the milestone last March, she said: "Okay then, I would [have sex with him].

"We could go out and buy lottery tickets, vote, play putt-putt golf. All the things that are legal at the age of 18."

The "Tik Tok" singer previously claimed she once had a sexual encounter with a ghost and her track "Supernatural" was inspired by the erotic paranormal experience.

She said: "I also have this song called 'Supernatural'. It's about experiences with the supernatural ... but in a sexy way ... I had a couple experiences with the supernatural ... I don't know his name! He was a ghost! I'm very open to it."
