Jennifer Lopez opened the 2015 American Music Awards with an energetic dance medley performance on Sunday night.

The 46-year-old singer, who also hosted the awards show, performed a myriad of her hits, while busting out impressive moves alongside a group of back-up dancers.

Lopez performed a slowed-down rendition of her 1999 hit song "Waiting for Tonight," before transitioning into a bunch of 2015's upbeat dance tracks.

"Tonight's not about me. Tonight is about the music!" she said. "And this year's music made me want to dance. Do you want to dance with me? This is a party. I said do you want to dance? Alright, let's dance."

The singer performed a medley of Mark Ronson's "Uptown Funk," Nicki Minaj's "Anaconda," Beyoncé's "7/11," The Weeknd's "Can't Feel My Face," Taylor Swift's "Bad Blood" and Drake's "Hotline Bling." She also slowed it down with a snippet from some Ed Sheeran's "Thinking Out Loud." Lopez added in Chris Brown's "Love More" and Justin Bieber's "Where Are Ü Now," before ending the performance with her version of Rihanna's "B*tch Better Have My Money."

When the camera cut to Minaj during Lopez's rendition of her track "Anaconda," several people on social media commented on the female rapper's facial expression and reaction to the performance, claiming she did not look too impressed.

However, Minaj laughed off the accusations on Twitter, saying, "lol says what all? I'm looking at my own face on the screen when I'm looking to the right. I turn Bak & look @ her."

Minaj took home two honors at the awards show, including Favorite Rap/Hip-Hop Artist and the Favorite Rap/Hip-Hop Album award for "The Pinkprint."

The 43rd annual American Music Awards were held at the Microsoft Theatre in Los Angeles and aired on ABC. J.Lo's full perfomance is available here.
