Angry viewers took to Twitter to vent about the raunchy performance. One viewer wrote:  “Think I have seen a little too much of Jennifer Lopez — meant to be a family show? #inappropriate #bgt.”

Another one said: “#BGT does #jenniferlopez realize it’s a family show — only thing missing was the pole – cover up your cheeks please!”

For the record, Lopez actually does grind on a pole about three quarters of the way through her performance.

The whole thing was enough to get British TV regulator Ofcom to release a statement confirming that “it has received complaints about the ‘Britain’s Got Talent’ broadcast last night, which we are assessing but not currently investigating.”

Lopez, however, seemed quite pleased with her appearance, tweeting afterwards:

Judge and show creator Simon Cowell was also full of praise for her performance. “Seriously, J-Lo. If anyone wants to know how you do it — that’s how you do it,” he said on the show. “Seriously, world-class.”

Cowell even tweeted later:

 

The performance may be a little too R-rated for the show’s demo, but there’s no denying Lopez has still got it. Watch below:
