We Hope She's Well-Rested!

Another Vegas night more hard-pAArtying from Britney Spears!

The mother of two and onetime golden pop star hit up the Pharrell soiree Tao on Saturday night, where she hung out for the second night in a row with new BFF Diddy.

She’s still got that look of crazy in her eyes!

And, Pharrell looks like a baked clam, though his friends insist he’s pretty straight-edge. Maybe he’s just slack-jawed?

Britney’s wild night also saw her make an appearance at the Hard Rock’s Body English club for the 50 Cent album release party.

She also stopped by Jet Nightclub for Cassie‘s 21st birthday party.

And, yes, she was boozin’ it up every step of the way!

You better turn it out at the VMAs, Brit. Just OK is not going to cut it!
