The iHeartRadio Music Festival 2013 brought together some of the music industry's hit makers such as Katy Perry, Chris Brown, Elton John, Robin Thicke - and of course Miley Cyrus. The festival took place September 20 to 21 in no less than Las Vegas.

Miley Cyrus' iHeartRadio Music Festival performance is her first after she and ex-fiancé Liam Hemsworth confirmed that their engagement was off Monday. The young singer performed her latest songs, "We Can't Stop" and "Wrecking Ball" on stage - thrilling fans and non-fans alike. She also did a rendition of Melanie Safta's "Look What They've Done to My Song."

Pop star Britney Spears introduced the younger singer who came out wearing a white and black ensemble. She wore white bottom underwear with a black criss-cross pattern over it and some black cloth patches on her chest. The outfit was topped off with a barely-there net cover-up and some furry long-sleeved bolero with neck accents.

Her teddy bear back-up during the MTV VMA 2013 performance of "We Can't Stop" has been replaced with mushrooms, rainbows and flowers dancing behind her all throughout the performance. At one point during the performance, the singer twerked - along with her back-up dancers of little people on stage. She even managed to slap one of those little butts!

Cyrus' then mellowed down with her "Wrecking Ball" performance that was highly emotional. The singer literally had tears streaming down her cheeks during that night's rendition of the song. With voice cracking and her mascara stained, she sang emotionally to the lyrics of the song.

Both "We Can't Stop" and "Wrecking Ball" are part of the young singer's upcoming album titled Bangerz. The album is slated to come out early October along with other tracks.

The video for "Wrecking Ball" is hailed the most viewed VEVO video ever and has landed the top spot in the Billboard Top 100.
