'Glee' star Matthew Morrison has a debut album coming out next month, but he's already been a part of a boy band, as Jay Leno reminded everyone the other night.

Morrison's fictitious boy band experience came in the 2003 Lisa Kudrow-Damon Wayans romantic comedy 'Marci X,' a film which Morrison jokingly refers to as "a fantastic piece of something." He played a member of a gay boy band called Boys R Us.

"I can't believe you're doing this to me right now," Morrison says as Leno introduced the clip. "It was the gayest thing I've ever done in my life, literally."

In the clip, the actor sports a thick, curly head of hair that would've made a late-'90s Justin Timberlake jealous. Morrison and his pink-wearing bandmates execute choreographed dance moves and sing about watching reruns of 'Will & Grace.'
