Britney Parties for Her BD, Paris Drops BFF

Britney Spears celebrated her 25th birthday with – who else – new galpal Paris Hilton, and they added another third wheel to their coupling, at least for Saturday night – Fergie of the Black Eyed Peas.

Sources say that the Britster dined at Mr. Chow's with her manager, Larry Rudolph, then nestled into a corner table with Paris and Fergie at L.A. hotspot Hyde, and walked "hand in hand" around the club until past 2 AM.

Meanwhile, Paris has gone all Mean Girl on former BFF Kim Kardashian, says Page Six, leaving her in the D-list dust after a much more high-profile friend presented herself. Kim "got shined for the more popular" – and more underwear-optional – girl.

George Clooney's 300-pound potbellied pig, Max, died last Friday. Clooney once told an interviewer that his longest relationship ever was with Max, his personal porker. The oinker had serious health problems -- he had arthritis and was partially blind. In 2001, Max was accidentally hit by a car driven by one of Clooney's friends.

Clooney has had the squealer for 18 years. He got porcine custody after his breakup with Kelly Preston. Tough year for Clooney; his bulldog also died earlier this year.

TMZ has learned exclusively that "Prison Break" star Lane Garrison displayed "symptoms of alcohol intoxication" after a crash involving an SUV he was driving that killed a 17-year-old boy late Saturday night in L.A, according to the Beverly Hills Police. We have also learned that alcohol containers were removed from Garrison's car. Two 15-year old girls were also in the car at the time of the incident and one is in serious condition at Cedars-Sinai Hospital.

Garrison has had other driving problems this year. Last October, a TMZ camera caught Garrison leaving Hyde nightclub, right after his Land Rover struck an Infiniti in front of him. The driver of the Infiniti began shouting, "Hey, stop the car, stop the car, you hit my car." Garrison saw our camera and pulled his jacket over his face.

As for Saturday's crash, Garrison hit a tree in Beverly Hills. The actor, who was not arrested, suffered minor injuries.

Jessica Simpson was so jittery during a tribute performance to Dolly Parton of "Nine to Five" at the Kennedy Center Honors yesterday that she abruptly walked offstage when the song ended, and when she reappeared onstage, she was still in tears. The blonde songstress finished her rendition of the Eighties hit with the words "so nervous" and bolted, to no applause. And then, when she and the other singers in the tribute to Parton came onstage later, Jessica was in tears. No word on whether Simpson's performance will be edited out of the broadcast, which will air later this month. Parton was recognized at the annual lionization gala along with Steven Spielberg, Andrew Lloyd Webber, Smokey Robinson, and conductor Zubin Mehta.
