Sounds like there's still bad blood between the bad boy and Jenny from the Block!

P.Diddy was being considered to fill the vacant third judging seat on American Idol... until ex-girlfriend Jennifer Lopez signed on to come back to the singing competition, that is!

The rapper passed on the opportunity after learning J.Lo was returning to the show alongside fellow judge Keith Urban. The hip hop mogul reportedly still has beef with the Latina singer and her longtime manager Benny Medina, who used to rep Diddy until they parted ways several years ago.

The "Last Night" lyricist "felt it was a 'her' or 'me' situation," a source tells Us Weekly.

Clearly producers chose her!
