Poor, poor Britney! The diary she wrote in while spending time @ the Promises rehab center in Malibu reveals her deepest, darkest secrets from why she shaved her head to how she never really loved K-Fed and how she was only using Paris to show the world that she was single and ready to party.

First, the dish on her hair… those pesky & painful extensions were apparently to blame for why Britney decided to shave her head on Feb.16. Yes, you heard it right! “It had nothing to do with any drug-test threats” says a friend.

Secondly, Britney Spears’ diary reveals a confession that she was never really in love with Kevin Federline; she was in LUST with him and found him amusing. Unfortunately, her plans of having children to bring them closer together didn’t really work.

Finally, Britney’s rehab diary reveals that she was only using Paris Hilton to get publicity about how she’s a girl gone wild hitting it up @ West Hollywood clubs. It also divulged that she grew tired of the paparazzi’s bad press (i.e. pantyless photos) and decided to cool it with her new BFF. All I have to say is you go girl! It’s about time Paris feels what it’s like to be dumped by a “friend”; she changes best friends like her underwear.

After dining at Koi, Nicki and Paris Hilton were spotted strutting into the new celeb hot-spot Winston’s in Los Angeles for a girls’ night out! Sources revealed to BestCelebGossip that they ducked out just before Lindsay made an appearance at the night club. Did the paparazzi miss out or what!?

After numerous touch-ups @ the Neil George salon, Lindsay Lohan turns blonde! Again. She also turned heads while out for dinner at Mr.Chow’s and then the hottest new club Winston’s on Wednesday night. From brunette to blonde, Lindsay looks fantastic but, we feel she looks stunning as a brunette. Tell BestCelebGossip what you think!

Take a look at her locks while outside Teddy’s last Saturday night. Dark hair suits her best! Also, Lindsay was seen flirting it up with Oscar nominee Djimon Hounsou on the way out. Rumour has it he was seen with Cameron Diaz and Kimora Lee Simmons, flirtatiously.

The Simple Life star and boyfriend Joel Madden made a brief appearance last Saturday night @ Mr.Chow’s in Beverly Hills. Nicole Richie was looking super fashionable in what could only be a Pucci dress. Props to her fab sense of style! Cutting the “evening” short, they didn’t stay long… sneaking out the back door of the restaurant as quickly as they went in.

Unfortunately, a paparazza is claiming that the Good Charlotte vocalist shoved her out of the way and is allegedly going to take legal action.
