Jennifer Lopez wore a dark purple fringed cardigan with flashing flesh panels, unintentionally revealing this flaw.

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.

She teamed her outfit with flesh coloured fishnet tights and high heeled lace up boots.

She wore her long light brown hair loose around her shoulders and flipped it in circles on top of the judge’s table at one point.

And at the end of the number, J-Lo sung a few bars of her hit single Jenny From The Block, much to the audience’s delight.
