Charli joined pal Iggy Azalea for a performance of "Fancy"

Charli had already been all over the 2014 AMAs, presenting the nominees along with Jason Derulo back in October. She also somehow made the time to join her pal Iggy Azalea for a live performance of their hit "Fancy" during the show.

London-based singer and songwriter Charli XCX is quickly proving an unqualified phenomenon with her edgy, yet addictive approach. Since her first critically-acclaimed track, “Nuclear Seasons” in 2011, the 22 year-old, Charlotte Aitchison, co-wrote the #1 smash single, “Fancy” with Iggy Azalea, and penned last year’s double platinum summer it-song, “I Love It” recorded by Icona Pop, which she is featured on. Most recently, Charli XCX released the platinum selling “Boom Clap” single from the The Fault in Our Stars: Music From the Motion Picture soundtrack, landing the #1 spot on Top 40 radio along with a brand new song, “Break The Rules,” from her forthcoming sophomore studio album Sucker arriving December 16th via Neon Gold/Atlantic Records.
