Cheyenne Jackson is the only openly gay Broadway star vying for the title of Broadway's Hottest Guy, but Kyle Riabko, who'll play gay on 90210 this fall, and gay-friendly John Stamos are also in the running.

Jackson appeared as Woody in this season's Broadway production of Finian's Rainbow. He rocked the lead role of Sonny in the Tony-nominated musical Xanadu. His film credits include United 93, a feature film that details the involvement of United Flight 93 in the 9/11 terrorist plot. In the film, he plays Mark Bingham, a gay man who is believed to have been among the passengers that stormed the cockpit of the plane.

The hunky star is also making waves on the small screen, appearing in a guest spot last season on ABC's Ugly Betty, where he played a gay dad. And he will star on ABC's new gay comedy It Takes a Village.

Jackson has signed on to play the role of boyfriend to Christopher Sieber (It's All Relative). Sieber plays a gay dad struggling to raise his teenage son after divorcing. ABC agreed in February to pick up the pilot for the single-camera comedy written by Casey Johnson and David Windsor (Greek) from ABC studios but the show's premiere remains unknown.

Canadian pop singer Kyle Riabko is transitioning from the stage of the Broadway revival of Hair to the set of the CW's teenage drama 90210, where he'll play boyfriend to Trevor Donovan's all-American jock character Teddy Montgomery.

John Stamos is also among the 16 men nominated for the title. Stamos, a vocal supporter of gay marriage, starred as Albert in Bye Bye Birdie on Broadway this season.
