Miley Cyrus was part of the star-studded line up at the 2013 iHeartRadio Musical Festival in Las Vegas on Sept. 21. 

The 20-year-old performed Wrecking Ball for the first time ever during a four-song performance at the iHeartRadio Music Festival Village on Saturday afternoon, an extension of the 2013 festival. The song is Cyrus' second Bangerz single and her first No. 1 song on the Billboard Hot 100 chart.

She took to the stage in white shorts and a matching cropped top as she launched into We Can't Stop with help from dancers dressed up as rainbows and mushrooms. After some twerking from a trio of little people on stage, Cyrus performed Party In The U.S.A. and her cover of Melanie Safka's Look What They've Done To My Song. She then went into Wrecking Ball.


Thel iHeartRadio Village is located across from the Luxor on the Las Vegas strip and included 20-minute performances by the Wanted, Avril Lavigne, Krewella and Jason Derulo, among others. Cyrus also performed on Saturday night at the MGM Grand Garden Arena, when the iHeartRadio Music Festival continued with Justin Timberlake, Paul McCartney, Drake, Bruno Mars and others.

For the evening set, Cyrus wore wearing pasties over her nipples and a tiny underwear under a fishnet cover-up. Britney Spears introduced her on stage and she began her performance with We Can't Stop. The two singers collaborated for the new track SMS on Cyrus' Bangerz album, which will be released Oct. 8.  She released the record's full track list on Tuesday, Sept. 10.

The Hannah Montana alum told The Huffington Post U.K. in July she can relate to Spears and how she has handled fame.

"Everyone goes through a time in their life where they don't want their picture taken every day," Cyrus explained. "She just never had that time where she could say, 'I'm going through something right now and need to shut down.' I also don't have that, so it's good to have that one person in my life who gets it."
