Jennifer Lopez gave UK viewers of Simon Cowell's Britains Got Talent a real eyeful on Tuesday night, performing her new single 'Live It Up' while wearing a skimpy black leotard that barely covered her famous behind. Twitter immediately sprang into action, with some parents concerned about the "inappropriate" nature of her performance on what is considered a family show, with some young children actually performing.

According to the Hollywood Reporter, a spokesperson for TV regualtor Ofcom said, "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." One viewer on Twitter said, "BGT does #jenniferlopez realise it's a family show - only thing missing was the pole - cover up your cheeks please!" though judge Simon Cowell was pretty happy with how things went, telling Lopez, "Seriously, J-Lo. If anyone wants to know how you do it. That's how you do it,' he said. "Seriously world class."

For what it's worth, Lopez herself seemed pretty oblivious to any concerns and happily posted an Instagram of the R&B star being held up by various dancers. "Thanks @GotTalent for a great night #liveitup," she added.
