That's cool.I dunno about Melo, but one of my roommates from SU was nominated for an Emmy for editing the credit sequence for that show.
(he was also nominated for a VMA for helping edit Kanye's video for Stronger)
Ah, I thought you were talking about FAB.
Anyway, a quick Google shows me Carmelo is indeed appearing on Nurse Jackie, and apparently filmed an episode of SVU as well. He probably won't be playing the role of a snitch in that one, I'm guessing.
