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 (11Oct12) 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 (22Oct12) 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 (20-21Oct12).
