Teenyboppers are wild for the all-glammed-out Lambert, whose performance of "Mad World" was a highlight of the American Idol season-if not the entire series. When, earlier this season, photos surfaced of him kissing other men, Lambert replied, "I have nothing to hide. I am who I am."

In 1976, the piano man announced he was bisexual (très scandalous for the time!) and then married a woman in 1984.

The former boy band member has always been coy about his sexual orientation-perhaps because so many of his fans are gay. But in 2005, the pants-averse Williams won libel damages from several newspapers and magazines that claimed he was secretly gay and had trysts with men in club bathrooms. "Mr. Williams is not and never has been homosexual," his lawyer wrote. So that's settled.

Perry's hit song "I Kissed a Girl" glamorized casual high school experimentation-in an effort to tantalize a boyfriend, she ends up revealing her interest in becoming a "switch hitter." Her other hit, "Ur So Gay" was not praised as much for its less-accepting tone.

The Puerto Rican star who gifted "Livin' La Vida Loca" to the world always had rumors swirling about his sexuality, but ducked the question while in the public eye. In late 2007 the tabloids were atwitter when his Swedish skin care specialist said in an interview that Martin was gay. Sadly, his pleather pants have now been hung up, as he takes on a new role as father to twin boys, born via a surrogate mother.

Early in his career, George Michael teamed up with fellow pop singer Andrew Ridgeley to form Wham! and create such '80s hits as "Wake Me Up Before You Go-Go" and "Careless Whisper."

Before Adam, Clay was the original American Idol alum dogged by rumors about his sexuality. The second season runner-up told Rolling Stone in 2003, "One thing I've found of people in the public eye, either you're a womanizer or you've got to be gay. Since I'm neither one of those, people are completely concerned about me." Five years later, after announcing he fathered a child with his female friend and producer, Aiken announced he was gay on the cover of People magazine, saying he had "no more secrets."
