WATCH: CHARLI XCX PERFORMS 'BOOM CLAP,' 'BREAK THE RULES' AT 2014 MTV EMA AWARDS (LIVE PERFORMANCE)

Wearing her very sexy jumpsuit, Charli XCX treats us with her punk flavor with her performance at the 2014 MTV EMA Awards.

British singer Charli XCX was "fancy" when she first performed her hit from "The Fault In Our Stars OST," "Boom Clap" before she became rebellious with her performance of her new single "Break The Rules."

Watch:
We will not be surprised if she will be picked as one of the best dressed of the night. =)
