Jennifer Lopez is reportedly returning to American Idol in a move that would make her one of the highest-paid judges in reality TV. Sources say JLO will pull in $15 million for a one-year deal. She'll replace Mariah Carey and work alongside Keith Urban and Ryan Seacrest. JLO reportedly approached Fox about returning because she wanted to settle in LA so her kids, 5-year-old twins Max and Emme, could start kindergarten. As for the seat left vacant by Randy Jackson, rumor has it Will.I.Am will step in. Stay tuned!
