PHOTOS: Jennifer Lopez Under Fire For inappropriate Dressing/Performance at the British's Got Talent.

She was there to give an exclusive performance of her new single, but Jennifer Lopez gave the audience and viewers of Britain's Got Talent a lot more than they bargained for as she took to the stage on Tuesday night.

The multi-platinum album-selling singer arrived on stage wearing a tiny black leotard that barely covered her famous derriere, and within moments both Twitter and viewer forums were awash with angry comments from BGT fans who were furious at the 'inappropriate' nature of her appearance.

And by Wednesday morning, broadcasting industry regulator Ofcom had been inundated with complaints from viewers who were unhappy to see such a raunchy performance on a family show.

A spokesperson for Ofcom told MailOnline: 'Ofcom can confirm that it has received complaints about the Britain’s Got Talent broadcast last night, which we are assessing but not currently investigating.'

 Fans of the show were left in shock as the superstar cavorted around the stage wearing little more than skimpy underwear, a bizarre fur bolero and thigh-high boots.
