NEW YORK, NY  [Thursday Mar.23.2006]  /RedBoxCode.com/ -- Patrick Stump has been doing a little moonlighting.

The Fall Out Boy singer recently took time out to make a guest appearance in a new video from his labelmates, Gym Class Heroes.

Stump can be seen in the clip for the track, "Cupid's Chokehold," from Gym Class Heroes' latest album "The Papercut Chronicles." Throughout the video, Stump is seen and heard singing snippets of the classic Supertramp song, "Breakfast In America."
