Matthew Morrison's Gayest Moment

Glee star Matthew Morrison told Jay Leno about the "gayest thing" he has ever done.

Morrison appeared in the 2003 film Marci X as a member of gay boy band Boys R Us, complete with a song with lyrics about Will & Grace.

"It was the gayest thing I've ever done in my life -- literally," he said on TheTonight Show Wednesday. They later showed a clip of a mock music video for the boy band, with the members donning pastels and displaying their corny dance moves.

"I really like your smiling face," they sang, "My beach house has a fireplace / We'll watch reruns of Will & Grace / And fornica-a-ate."

Marci X stars Lisa Kudrow, whose character is attempting to save her father's failing music company and must convince a controversial hardcore rapper, played by Damon Wayans, to apologize for his offensive album.
