Taylor Swift channeled her inner rock star during her performance at the iHeartRadio Music Festival in Las Vegas on Friday night, Mirror reported.

Dancing is not one of Swift's strong suits, but it looked like the singer had the time of her life, jumping on stage and even dropping to her knees at one point in the show.

Swift kicked off the music festival with a five-song set, which included her past hits "Love Story," "22," "I Knew You were Trouble" and "We are Never Ever Getting Back Together."

But the young singer, who donned a pink cropped top and skirt, stunned the crowd when closed the set by belting out her new smash single, "Shake It Off," according to a Billboard report.

Swift took to her Twitter account after the performance to thank her fans, saying "I was so happy tonight, it made it impossible to remember the times in the past that I haven't been."

Aside from Swift, the festival also had Nicki Minaj and Ariana Grande do some serious butt moves during their performance.

Minaj first performed her hits, such as "Super Bass," before moving on to her verse in Beyonce's "Flawless" remix. The singer, however, had run into technical difficulties, which prompted her into performing her verse a capella, according to Idolator.

Later in her set, Minaj called Grande to join her on stage when Jessie J's "Bang Bang" started playing. The young singer belted out the high notes and danced to Minaj's verses. Minaj, Grande and Jessie J first performed the song live at the MTV Music Awards, where Minaj has a wardrobe malfunction.

Coldplay was also at the MGM Grand Hotel and Casino for the two-day festival, and frontman Chris Martin's rumored new love, Academy Award winning actress Jennifer Lawrence was spotted making her way backstage shortly before the band's set started, according to Mail Online.

The 37-year-old singer didn't disappoint Lawrence and his fans, belting out ballads while dancing around the stage. At one point, Martin threw himself backwards while sitting and playing at the piano.

Other artists who were also in attendance during the festival include Bastille, Jason Derulo, Chris Brown and Usher. The event is scheduled to continue on Saturday night with sets from 5 Seconds of Summer, One Direction, Lorde and Ed Sheeran.
