GIRLS GONE WILD (kitty kitty)
Britney Spears spent every night of Thanksgiving weekend in Los Angeles partying until 6am with new BFF Paris Hilton and the late nights are taking their toll.
A source tells the New York Post: "Britney has been missing recent recording sessions because she has been out all night partying. Her label, Jive, is very worried."
The troubled pop princess, who has two young sons, Sean Preston and Jayden James, has been telling her friends: "I gave birth for two-and-a-half years, and now I want to party."
