The uneasy singer, who supposedly once tried to seduce her children’s nanny and was photographed romping topless in a pool with former assistant Shannon Funk, revealed her desire for Kim during a tell-all game with friends.

When asked which celebrity she would most like to have sex with, Britney reportedly said: “I really love Kim’s butt, skin and hair. Kim is a real woman. She is a real horny beast.”

Kim, who caused a pandemonium in the US after her homemade sex tape with ex-boyfriend Ray-J was released, isn’t the only brunette beauty admired by Britney.

The singer also revealed she lusts after stunning actresses Carmen Electra and Halle Berry, while Brad Pitt and George Clooney top her list of sexiest men.

A source said: “She was so graphic. It’s funny to hear America’s pop darling get so dirty.”

Pop star Britney Spears reportedly allowed a man to snort cocaine off her chest during a wild party at her Hollywood mansion.

Guitarist Scott Kohler has claimed that the 25-year-old singer invited him and ten other strangers for the party - two days after she lost visiting rights to her kids.

The 29-year-old man said that Spears downed vodka, then stripped to her underwear and said: “Let’s get in the Jacuzzi.”

Kohler alleges the singer accepted an offer of cocaine from a fellow partygoer, after he “joked he wanted to do a line off her chest, and she agreed.”

He also claimed that she “seemed drunk” and took coke herself. But she still passed a court-ordered drug test the next day.

“She was in a great mood. She didn’t have a care in the world,” The Sun quoted Kohler, as telling In Touch magazine.
