Jennifer Lopez opened the AMAs last night with a very lengthy and energetic number, but unfortunately for one of her dancers, she exposed way more than she intended. 

The 46-year-old kicked the night off with a dance routine medley of the biggest hits of the year with songs from Rihanna and The Weeknd.

But towards the end of the act, one dancer flashed a LOT of cheek after her catsuit split and revealed her entire bum – and the whole thing was caught on camera. 

Eagle-eyed viewers that witnessed the embarrassing moment took to the Internet and social media was quickly abuzz. 

But one member of the audience that look less than impressed throughout the whole routine was Nicki Minaj.

Nicki threw some serious shade while Jennifer was dancing to her song Anaconda. But apart from that the whole crowd went wild for J-Lo.

Here's a video from the Daily Mail to show you the small incident:
