Jennifer Lopez has yet to officially announce that she's the newest judge on 'American Idol,' however, sources tell me the job only became hers after several big-name celebrities said "thanks, but no thanks."

"J.Lo was definitely not the first choice," an 'Idol' insider tells me. "In fact, she wasn't even the second or third choice."

My source tells me that before they approached Lopez, producers first asked Elton John and Barry Manilow to join the hit -- but starting to struggle -- show. Both are undeniably great singer-songwriters who have mentored contestants in prior seasons, so it wouldn't have been a stretch.
