Openly gay celebrities Clay Aiken, Alan Cumming and Denis O'Hare will star in the one-night-only production of Broadway Backwards 6, all-things-Broadway website reported.

The February 7 show will benefit Broadway Cares/Equity Fight AIDS and New York City's Lesbian, Gay, Bisexual & Transgender Community Center (the Center).

Broadway Backwards flips the originally intended gender of crooners singing popular Broadway tunes.

Thirty-two-year-old Aiken rose to fame on the second season of Fox's reality talent show American Idol. He's since gone on to record six studio albums and star on Broadway in the musical revival of Monty Python's Spamalot.

Tony-winning actor Alan Cumming (Cabaret) can currently be seen on CBS drama The Good Wife. Cumming, an early Obama supporter, created a stir when he called the president a disappointment on gay rights.

Denis O'Hare won his Tony for Take Me Out, but has gained fame on HBO's vampire drama True Blood.

Broadway Backwards 6 will also feature Tituss Burgess (The Little Mermaid), Len Cariou (Sweeney Todd), Kevin Chamberlin (The Adams Family), Robin De Jesus (La Cage aux Folles), Jose Llana (The 25th Annual Putnam County Spelling Bee), Lin-Manuel Miranda (In The Heights), Debra Monk (Curtains), Bobby Steggert (Ragtime), Brian Charles Rooney (The Threepenny Opera) and Tony Yazbeck (Gypsy).
