ET's Jann Carl goes one-on-one with Clay Aiken, who talks candidly about being a doting daddy to his baby son Parker, and about his decision to come out to the world as a gay man.

Clay is back on Broadway, reprising his starring role of Sir Robin in Monty Python's Spamalot. The multi-talented music man tells Jann he actually returned to the stage to enjoy more family time at home with three-and-a-half-month-old Parker and the baby's mother -- Clay's good friend -- Jaymes Foster.

The "American Idol" finalist also admits he was "terrified" about performing on Broadway the week after he revealed his sexual identity, fearing he'd get booed off the stage. Naturally, he drew the opposite reaction -- rousing cheers and applause -- instead.
