Mary Carey may be in Vegas to celebrate her 28th birthday - but there's no law that says you can't do a little shillin' at the same time!

Mary was sweet enough to pose for a few sensuous photos with a pair of cups emblazoned with stickers advertising the new energy drink Blow. Of course, she was even sweeter to her boyfriend David Weintraub, swapping a little spittle with the Son of Hollywood for the benefit of the cameras. Don't they make a classy couple?

...Crown Bar was jumping off like crazy! We caught Evan Ross, Sean Stewart, Bret Ratner, Robin Thicke - heck, Crown Bar's so hot right now that even Nicole Richie and Joel Madden had to pull themselves away from diaper duty for a night!

Of course, the night's most surprising entrance had to be Mary Carey's - not only did she manage to not say something embarrassing (for once), but she swore up and down that her date with David Weintraub was "strictly business"! (And wait until you see Mary's take on "business casual"!)

Mickey Rourke was flashing some flesh! We caught up with the Rourkester leaving Mr. Chow rocking the ol' shirtless blazer look. 'Course, we can't hate too much - after all, just look how hot a date he landed with that trick!

Of course, Mickey wasn't the only celeb who stopped by the legendary eatery for a bite - a scant while later, we caught legendary designer Christian Audigier and Brittny & Lisa Gastineau taking off after dinner! Elsewhere, Ryan Phillippe ducked the paps outside of the Roosevelt, Elliot Mintz spoke his piece outside of Foxtail, Mary Carey and Charles Barkley hit up Goa, and Rick Salomon has words for Paris Hilton's main squeeze Benji Madden - you hope he's whating it good, Rick?

Where did half of Hollywood go after the Maxim party? Crown Bar, of course!

The hot spot saw the likes of various celebs Wednesday night, including Brit's old pal Alli Sims (in a leopard-print dress), Audrina Patridge (who didn't stay long as her friends weren't allowed in), Nick Lachey (sans Vanessa), Lauren Conrad (with Lo, not Audrina!) and even the epitome of grace, Mary Carey.

In fact, there were so many stars and starlets out last night that we put together a gallery for your viewing pleasure...

One of our spies spotted Mary Carey - star of VH1's Celebrity Rehab (and, um, a few thousand porn movies) - vigorously enjoying a cold one last night outside the Hard Rock Cafe in Vegas! Jeez, Mary - didn't you learn anything from Doctor Drew?

(And of course, we couldn't possibly pass up the chance to link back to our favorite Mary Carey clip of all time - how's that rap album coming, Mary?)

Although she's far from the first celeb to register her opinion on Paris' upcoming 45-day stay in the Linwood Hilton, we couldn't resist getting the ever-entertaining Mary Carey to go on the record regarding the hotel heiress' legal woes - and boy did she ever go on the record! Mary certainly didn't hold anything back as she went in-depth discussing the foibles of the justice system - but then again, restraint's not exactly Mary's strong suit!

What, you thought you'd heard everything Mary Carey had to say earlier today? Well, guess again, because after Scott split, Mary came back out and addressed a wide range of subjects - midgets, her forthcoming hip-hop record, her willingness to make out with random dudes in the street. (And don't go thinking it's over when you hear the paps start to applaud - well, unless you don't want to hear her message to Mariah Carey!)
