It was supposed to be a mellow L.A. event but quickly turned into a redneck free-for-all when Britney Spears and her crew rolled in. Britney and her only two friends, Sam Lufti and Alli Sims, arrived at the Scandinavian Style Mansion around 10 pm Saturday night where Sharon Stone was hosting a party to help introduce some Scandinavian brand to the U.S. Little did everyone know it was about to become the setting for Britney and crew to celebrate her 26th birthday.

After hitting the swag area for tons of freebies, Brit and co. popped back out to the chauffered Range Rover for 15 minutes (insert your own drug joke here) then right back to their private table where Britney’s “friends” presented her with a small hoopty chocolate cake and sang Happy Birthday to the popwreck. The party really got started about 11:30pm when Paris Hilton arrived and joined in her former BFF’s celebration. If these pictures are any indication, neither girls harbor any ill feelings and in fact partied together at the Four Seasons in Beverly Hills until sunrise.

We are pained to admit that next to Britney, Paris looks absolutly gorgeous.
