Jennifer Lopez was left overexposed once again during a London stop on her world tour when she suffered a nipple slip during an energetic routine.

The singer experienced a wardrobe malfunction at a show in Italy earlier this month when her sequinned catsuit slipped as she danced, baring her right breast.

And the On The Floor hitmaker was left red-faced again while performing at the O2 Arena in the U.K. capital on Monday night when the same catsuit failed to keep her assets in place, leaving her nipple showing through the costume's transparent mesh.

Lopez wasn't the only superstar who had a fashion faux pas in England this week - her American Idol successor Nicki Minaj also suffered a nipple slip while performing in concert in Nottingham over the weekend.
