New Celeb BFs {best friends} are Paris Hilton and Britney Spears.

They allowed Lindsay Lohan into their girl time over the weekend as well. Why do I feel Britney seriously downgraded?! How on Earth did Britney ditched K-Fed for Paris?!?! No I am not implying anything but I prefer K-Fed...hate to say that. Paris of all people is Britney's new celeb best friend?!?! WTF?!?!

"The clubbing may be over (at least for this weekend), but the fun continues for Britney & Paris, who pick up Lindsay Lohan in Beverly Hills during their girl-time marathon in the early hours of Monday morning. The trio stopped off at Hilton's pad before heading to Spears's place."

"New It couple Spears and Hilton make it two dates in a row at Hyde Lounge. On Saturday night (left), they matched their one-legged thigh-highs and hung out with the Olsen twins at the Los Angeles club, while on Friday night, "Paris was acting like Britney's boyfriend," a source there tells PEOPLE. "She opened doors for her, held her hand."

"Earlier on Saturday Spears introduces Sean P. to the art of shopping with Hilton as the trio stop by trendy Malibu boutique Planet Blue."

STOP THE DAMN MADNESS, PLEASE!

But wait this new best friend relationship gets even better!

"Whatever else they had to be grateful for this Thanksgiving, Paris Hilton and Britney Spears certainly seemed glad to have each other around. The pair, who hung out in Las Vegas the previous weekend, hit the clubs together in Los Angeles almost every night over the holiday week and even went shopping in Malibu together with Spears's son Sean Preston in tow on Saturday evening. They kicked off their girl-time marathon on Tuesday, when Spears, 24, went to a post-American Music Awards party Hilton, 25, hosted at her West Hollywood home. The following night, they were spotted at Teddy's at the Roosevelt Hotel in matching leopard-print outfits. (Spears's estranged husband, Kevin Federline, was hosting an album party across town at Republic the same night.) On Friday, Hilton left her sister Nicky and friends at the nightclub Les Deux to pick up Spears. The pair stopped at Hyde Lounge before eventually heading back to Les Deux just before close.
Blog: Comment on Her New Solo Look Finally, on Saturday night, after their shopping trip with Sean Preston, the duo were back at Hyde partying with the Mary-Kate and Ashley Olsen. "Paris was acting like Britney's boyfriend," says a source who saw them at Hyde on Friday. "She opened doors for her, held her hand, and even had her arm around Britney's lower back. Britney happily accepted Paris' friendly gestures." Spears filed for divorce from Federline earlier on Nov. 7 after two years of marriage. "

{I guess this is Britney's way of letting K-Fed know she can still party hard?!?!}
