Jennifer Lopez suffered another set of wardrobe malfunctions during her arena tour, suffering a nip-slip yet again, and showing off some spanx under her costume.

Lopez was performing at her “On the Floor” concert in Italy on Thursday, and perhaps she was dancing too hard.

The former “American Idol” judge is no stranger to wardrobe malfunctions, and her stage performance can’t be shaken by a nip-slip or two.

But Lopez may want to get stronger dress tape after revealing her breast in a plunging skintight cat suit while singing "Waiting for Tonight."

Besides her breast, the 43-year-old singer also flashed her spanx underneath, adding to the embarrassingly long list of celebrity wardrobe malfunctions.

At the 2012 Oscars, JLo was thought to have experienced a nip-slip, which suspicion her rep dismissed as an “illusion.”

"The Oscar dress was custom made for Jennifer by designer Zuhair Murad. The dress fit perfectly to her every inch. There were cups built in and there's no chance that there were any how do you say? 'slips,'" Lopez’s stylist Mariel Haenn said in a public statement.

"While the dress did give the illusion of sheer-ness, jokes on everyone who wishes they saw something! If you thought that dress was hot wait until you see what's next."

This time around, Lopez has no excuse for revealing too much on stage.
