Britney's Wild Night

Considering the last two days of Britney Spears' life, in which a former bodyguard came forward to allege that the pop star abused drugs and alcohol, and the judge in her ongoing child custody battle ordering her to undergo regular testing for illicit substances and to meet several hours a week with a parenting counselor, you'd think the last place she'd want to be seen was out and about is an L.A. club. Well, you'd be wrong.

At 12:45 a.m. last night, OK! witnessed Brit exiting L.A. club Winston's with Avril Lavigne and a handful of others. They all piled into a black Cadillac Escalade and headed over to Hyde nightclub, where they met up with other young celeb-types, including Cisco Adler and Leelee Sobieski.

While Avril made her exit from Hyde at 1:45 a.m. with billionaire layabout Brandon Davis and Britney's cousin, Alli Sims, Britney remained inside until after 2 a.m., at which point she slipped out in a white Mercedes convertible with a female friend.

No word yet on whether or not the pop princess needs to be worried about failing that first court-ordered test.
