H'wood Party Girl

Christian Audigier, the man behind the Ed Hardy tattoo tees, is bringing his over-the-top tackiness to Vegas, just in time for the Fourth of July.

The designer, who threw a huge birthday blowout attended by Britney Spears and Michael Jackson in L.A., has a club named after himself opening in Treasure Island this Thursday.

But will the turnout be as A-list as his last bash?

So far, Nick Cannon is confirmed to deejay the party, which means Mariah Carey might also be in the house.

But considering his birthday fete not only featured cameos from Brit and M.J. but performances by Fergie and Snoop Dogg, something tells us that bash will be tough to beat.

No word on whether bejeweled trucker hats are required for entry...
