Spears, 24, filed for divorce last Tuesday from failed rapper Kevin Federline. She asks for custody of their two sons, 1-year-old Sean Preston and Jayden James, who was born Sept. 12.

Federline, who's been making the rounds promoting his hip-hop debut, "Playing with Fire," counter-filed court papers also seeking sole custody and spousal support.

Michael Sands, a rep for Federline's lawyer, Mark Vincent Kaplan, tells PEOPLE that Federline's effort to gain sole custody of his children with Spears, Sean Preston, 1, and Jayden James (born Sept. 12) is not a money play.

Prostitute Danielle Coakley, 20, has told how she took drugs and partied with Federline while Britney was pregnant. She said: "Kevin was a real party animal. We went to two casinos then back to his hotel suite in Vegas. There were lots of drugs- cocaine, weed and ecstasy. We shared an E in his limo on the way then passed out on his bed." And 1000-a-night stripper Vanessa Hulihan, 30, revealed she spent weekends with him.

She said: "Kevin said we could be together if he wasn't married. Another time I went to his hotel suite and the tub was full of strippers."

Kevin was also seen blowing thousands at gambling tables while cuddling up to porn star Kendra Jade, 29.

In other news, Britney Spears has reportedly been turned down by fashion magazine Vogue.

Britney had hoped that the glossy magazine would run the first pictures of the pop star with her new baby son Jayden James, but they have knocked her back.

A source told Star magazine: "She really wanted the photos to run in Vogue, but they turned her down,"
