Fall Out Boy's upcoming album, Infinity on High, will feature hip-hop entrepreneur Jay-Z (aka Jigga-man, J-HOVA). Jay-Z does a voiceover at the beginning of the album, stating the album is dedicated to the fans that supported us/ the fans who held us down. In a recent interview with MTV, the band said the following about the rapper's appearance:

I think he recorded some of it in Australia while we were sleeping. It was insane. We called him up and thought we were gonna talk to his assistant. Then he answers the phone, like, 'Yo, this is Hov,' and we were like, 'Um …' It just happened like that. And it was pretty crazy.

Fall Out Boy's new album Infinity on High is scheduled for release February 6, 2007. Jay-Z released Kingdom Come last week, his first since returning to hip-hop from "retirement".
