Britney Spears Celebrates 26th Birthday, Crashes Sharon Stone's Party

December 3, 2007

Weaved pop-wreck Britney Spears celebrated her 26th birthday on Saturday (Dec. 1) at the Scandinavian Style Mansion in Bel Air, Cali., with attached-at-the-hip BFF Sam Lutfi and cousin Alli Sims, reports OK! magazine.

What started out as a private bash hosted by Sharon Stone (in which the actress was helping introduce popular Scandinavian brands in the U.S) escalated to a full-blown hullabaloo when Spears arrived with her entourage shortly before 10 p.m. (See photos here.)

Brit and her posse took a seat at a private table on the patio and, at one point, returned to their chauffeured Range Rover (reportedly for a bit of "fresh air") before returning 15 minutes later, reports OK!.

Around 11 p.m., the birthday gal was presented with a small, round chocolate cake while her friends and guests sang "Happy Birthday." The mayhem didn't end there: shortly before midnight, Paris Hilton made an appearance to the delight of the paparazzi, several of whom reportedly wet themselves they were so excited.

Naturally, the camera-loving heiress stole the spotlight.

"Paris drank in the attention," one witness tells OK!. "Posing for the camera and eating it up."

Apparently, there was no ill-will between the two former BFF's, who later sauntered over to the Four Seasons in Beverly Hills and partied until sunrise, sipping champagne and posing for pictures on the balcony, reports OK!.

"She was smiling and looked really happy," one partygoer said of Spears.
