J-Lo as American Idol judge!

It's happening, after all. Jennifer Lopezu00a0 is set to become a judge on American Idol, an insider confirms. Final contracts are currently being signed by Lopezu00a0-- plus Randy Jackson and fellow newcomer Steven Tyler, with an official announcement expected in early October, before auditions begin for the new season.

After a long negotiation process, "it ended up working out and they have a good agreement," the source tell. The star's rep had no comment. The insider adds that Lopez, 41, was selected as replacement for recently departed judge Kara DioGuardiu00a0-- not Ellen DeGeneres, who quit the show on her own accord.
