Apparently it's because he feels like it would be too awkward to work along side his ex Jennifer Lopez! We pretty much know now that J-Lo is coming back for another season on Idol - which we're very excited about but there is still one more seat that needs to be filled at the judges panel! A few names have been thrown out Will I A.M. - Scooter Braun, Kanye West and Dr. Luke however it seems an offer was made to Diddy, BUT he turned it down!
Do they still have bad blood???? I actually think it's the opposite, I think they have so much chemsitry that they don't want to ruin their current relationships! AHHH that would be sooooo good! Imagine. See Diddy is in a relationship with singer Cassie and J-Lo is with Casper. This would make for great TV - Diddy and Jennifer hook back up and then BOOM Cassie and Casper get together! :)
