Do you believe in life after an Oscar, a variety show, an ex-husband dying on a ski slope, a transgender child and gazillions of gay fanboys? Then you believe in Cher, who’ll be playing in Dallas on March 26, the third stop on her Dressed to Kill Tour. The gays love their uber-diva more than Judy herself, and the No Tie Dinner and Dessert party knows its audience. So, before the big fundraiser for AIDS Services of Dallas on April 12, the group is giving away tickets so any gypsies, tramps and thieves can see Cher in concert. Just pre-register for the No Tie Dinner now through March 19 at NoTieDinner.org, and you’ll be entered in the drawing. Don’t be late, though, because you can’t turn back time.
