She returned to the judges' table this season to pass her wisdom on to hundreds of pop wannabes on American Idol.
But on Wednesday's finale, Jennifer Lopez letting her performance do the talking, as she took to the stage for a powerhouse performance of her new single First Love.
Sporting a plunging purple fringed leotard with flesh flashing panels, the 44-year-old actress and singer shimmied her way through the number.
The new song appears on J-Lo's forthcoming A.K.A. album and her first performance after scooping the icon gong at last weekend's Billboard Awards.
'Such a fun night on #IdolFinale #JLoFirstLoveonIdol #moretocome #JudgesRockIdol,' Jennifer tweeted after the performance.
