It’s official: Britney Spears has become a caricature of herself. You honestly just can’t make this shizz up. On the night before she was expected in Las Vegas for rehearsals for the VMA’s, Brit Brit thought fit to do what she knows best…show up to a club wearing her token fedora/no-pants combo. Sponge Brit No Pants! Hole in the pantyhose sold separately. Us Magazine reports:

The night before she was expected in Las Vegas to rehearse her single “Gimme More” with illusionist Criss Angel, the perennial party girl, 25, hit up L.A. club Opera.

Accompanied by her cousin Alli Sims, Spears — clad in a cream fedora, gray mini-dress with stockings, knee-high boots and long pearl necklaces — settled into a corner booth around 12:32 a.m. (Her wig of choice? A blonde, shoulder-length number.)

“Britney was in a great mood all night, smiling, laughing, upbeat,” a witness says, who adds that Spears also smoked a few cigarettes and danced to Rihanna’s “Umbrella.”

“She was really getting into the songs,” the onlooker says.

Apparently, she worked up a thirst: “Britney drank beer, vodka cranberry and vodka tonic,” says the witness.

Sucking a lollypop, Spears left hand-in-hand with Sims at 1:45 a.m.

Alas, the two called it a night after hitting a Wendy’s drive-thru around 2:20 a.m.

Nothing says comeback like showing up half-cocked and bloated! You go Brit!
