Just two days after a Los Angeles judge ordered Britney Spears to undergo random drug and alcohol testing twice a week in order to keep custody of her two toddlers, Britney’s mom, Lynne Spears, received a phone call chronicling an Ecstatsy party attended by the fallen pop star.

“It was one of Britney’s friends saying he’d seen Brit take four Ecstasy pills in the bedroom of a Hollywood Hills home during a party on Aug. 11,” an insider reveals to Life & Style. “Lynne was also told that Brit’s done the drug more recently – and she’s taken Ativan, an anti-anxiety medication, to help her come down because the Ecstasy was so intense. Lynne put down the phone and froze.”

“Britney needs to go to rehab,” says another Brit insider. “It’s the only chance she has to save her sons.”

“There’s no way Britney’s going to let someone tell her how to take care of her boys.”

“She immediately ordered shots of Jgermeister,” a spywitness tells Life & Style of Brit’s recent club night at Winston’s “She seemed to be on a mission to get drunk.”

“It seems an impossible task for Britney to live up to all the judge’s demands,” says a friend of the star. “She’s freaking out about the random testing.” Those close to Britney certainly want her to get the help she needs.

“Her people are urging her to try Cirque Lodge in Utah, where Lindsay is.” “If Brit finally acknowledges that she must face her addictions, then that’s the best place. It’s working for Lindsay, and hopefully Brit will see that as inspiration.”
