Did she look like she was a stripper who stumbled in from the Spearmint Rhino down the Strip and had no clue what she was doing? Could she have been troubled to maybe dance a little or perhaps even know the lyrics to the song she was lip-synching. I’ve seen more effort from people in iron lungs. And where was that greasy magic guy’s “illusion”? Was the illiusion how her fupa didn’t intrude? Cuz staying up til’ 3 AM drinking the night before usually doesn’t result in someone looking that presentable. Then again, maybe that weave was the one out drinking til’ 3 AM. Yikes. Britney was out on Saturday night in Vegas doing the party circuit with Diddy. MTV warned her ass against that kind of thing! Does he imagine Sienna Miller when he docks in her space station?

With her new pal Diddy by her side, Britney Spears declined to stay in and rest up for the big show, instead bouncing from club to club along the Strip, and even hanging with Paris Hilton.

Aaiiieeehh!! Is she crazy (yes)? That bitch backstabbed your ass last time you hung with her! Plus, she’s a convict! Even Diddy didn’t go to jail for that club shooting! Keep reading for the details of what clubs she hit and with who. And what MTV told her NOT to do.

Many more photos of Britney Spears, Sean Combs, 50 Cent and Paris Hilton partying in Vegas are after the jump.

After taking in a Saturday-night performance of Cirque du Soleil’s Mystere with four friends, Spears headed to the Hard Rock Hotel’s Body English for the 50 Cent album release party.

Then around 1:30 Sunday morning, Spears and Diddy, along with an entourage of about 20, headed to Tao Nightclub for the Samsung party hosted by Pharrell. There, Spears – dressed in a champagne-colored dress, oversized sunglasses and a grey fedora hat – sat with BFF Alli Sims drinking vodka and sugar-free energy drinks.

Next stop: Jet Nightclub, to help celebrate the 21st birthday of R&B star Cassie. Arriving sans glasses and hat, Spears and Diddy made their way to Cassie’s VIP table, and the popster gave her a hug.

Actually, that sounds like a hot night. Diddy’s slumming something fierce lately. Is he trying to get her ass on “Making the Band”? Is this part of the Diddy Crazy White Girl Rehabiliation Program? MTV had told her to keep her shit together.

MTV officials had warned the pop tart to keep it clean for thelive Las Vegas broadcast. Britney was told that if she acted out before yesterday’s sound check she could be booted fromthe show.

So the mom of two played it safe, taking baby steps around the stage instead of showcasing her signature dancing skills.

No, you SHOULD have used your dancing skills. They just meant they didn’t want to see you using those dancing skills to earn shots in the club the night before by backing it up onto people! We were all counting on you to kick ass at your “comeback performance” and you barely broke a sweat. There’s quadrapelegics who could have done better. At least there would have been some artful wheelchair rolling and a hot respirator solo. And hopefully with less plunked on lookin’ weaves!
