Image Credit: FoxJustin Timberlake‘s been teasing fans of his singing for a while now. It’s been more than four years since his last album. And aside from an appearance here and there, he’s spent most of his time in Hollywood, refining his acting chops in box office heavy hitters like The Social Network. This Sunday (Feb. 20) on Fox, however, we’ll get the chance to hear a new song from the onetime full-time crooner. There’s just one catch: He’ll be singing in character–as a booger. On The Cleveland Show, Timberlake will play the last snot rocket to be shot from Cleveland’s stepson Rallo’s nose.

Check out a clip of the show after the jump.

“Rallo’s trying to kick his booger-eating habit because it’s turning all the girls off,” reveals show co-creator (and Rallo’s voice) Mike Henry. “It’s basically a goodbye ballad between Rallo and his last booger. We based it on ‘On My Own‘ with Michael McDonald and Patti LaBelle.” Justin loved the idea from the beginning and it didn’t take much time for him to get comfortable with his role at the studio either. “He just busted into this sweet falsetto as this little booger,” Henry says. “He got it down pretty quick.”

What do you think of Justin and Rallo’s duet? Will you be tuning in this Sunday to watch the whole show? Let us know.
