Britney Spears has been slammed by critics for heading out on an all-night partying session just hours after a judge ordered her to undergo random drug testing.
The troubled singer, who appears to wish to continue her wild ways, was spotted at Hollywood club Winston's with miserable pop star Avril Lavigne, before she moved on to the Hyde Lounge.
While at the celebrity haunt, Britney was said to have danced on table tops until the bar closed in the early hours of the morning.
Photographed looked well past her best, with a rolled up top revealing her belly and thick black glasses on, Britney was said to be a little the worse for wear.
An onlooker told American magazine People: "They kept bringing her shots and so they were drinking."
"She was dancing on the tables trying to be really sexy, even putting a black sock over her head as a hat, and putting on a show for everyone."
Britney had earlier that day been ordered to undergo random drug testing by the judge ruling in her custody battle for her children.
