Tara Conner Celebrates 90 Days Sober

Mess USA Tara Conner isn't letting a little thing like 90 days of sobriety get in the way of her partying!

The rehabbed beauty queen celebrated her first three months of sobriety with a party at a Hollywood nightclub. Cheers! 51 of Tara's closest pageant contestant friends -- and the press -- came out to Social Hollywood to, er, toast Tara on her crowning achievement. Britney , Lindsey ,Tara and Paris were invited, no word on if they were able to break free of rehab to join in with the celebration...Trump that!
