Jlo performs dazzling dance medley at AMA

Jennifer Lopez blew the audience away with an amazing opening number to kick off the 2015 American Music Awards. She danced along to samples of some of the night's nominated songs, before going on to host the show.

Wearing a glittery catsuit in multicolored Native American patterns, she opened with lines from her hit “Waiting For Tonight”, before going on to perform pieces from Bruno Mars' “Uptown Funk”, “Feel Myself” by Beyonce and Nicki Minaj, Little Big Town's “Girl Crush” to Taylor Swift's “Bad Blood”, Beyonce's “7/11”, The Weeknd's “Can't Feel My Face” and Drake's “Hotline Bling” – which got the biggest applause from the crowd as it's sample came on, and softer numbers like Ed Sheeran's “Thinking Out Loud”, before finally closing with Rihanna's “B**ch Better Have My Money”.

While Justin Bieber danced along in the audience with J-Lo's on-stage performance of his song “Where Are U Now”, Nicki Minaj looked very uncomfortable as Jennifer grooved to a section of her hit “Anaconda”.

She continued to surprise throughout the evening, going through a whooping 10 wardrobe changes.
