Irresistible is a great new song from Fall Out Boy which is right in line with the stuff they have been releasing of late and this go round they also bring in Demi Lovato to guest on the vocals with Demi complementing lead singer Patrick’s voice quite well. The video is pretty humourous too and features cameos from Nsync’s Joey Fatone and Chris Kirkpatrick, which is not something you see everyday, and continues the story from N Sync’s It’s Gonna Be Me video.
