Jennifer Lopez’s back-up dancer exposed more than intended during the singer’s show-stopping opening performance at the American Music Awards on Sunday.
The 46-year-old kicked off proceedings by performing a lengthy and energetic dance routine to a medley of the biggest hits of the year including songs by The Weeknd andΒ Rihanna, as well as her own hit from 15 ago, Waiting For Tonight.
But towards the end of the act, one of her dancers flashed quite a lot of cheek after her catsuit split and revealed her underwear during the very energetic show.

Eagle-eyed viewers witnessed the embarrassing moment, which was caught on camera on ABC, and social media was quickly abuzz.
Lopez’s performance was one of the many highlights of the night.
The crowd went wild – except for Nicki Minaj who looked distinctly unimpressed when the camera panned to her while J.Lo was dancing to Anaconda.
Lopez performed double duty – performing and hosting the ceremony – and managed nice costume changes.

Ariana Grande beat Taylor Swift and Trainor to be named favourite pop/rock female artist. She collected the award from singer Paula Abdul, who won the same award in 1990.

He added: ‘Tonight we honour the victims of the unimaginable violence that took place in Paris and around the world.
