Who loves it? Do you love it? We love it. And synth pop duo Icona Pop and British singer Charli XCX love it, too. Icona Pop brought Miss XCX on the stage to perform their collabo hit 'I Love It' last night (March 12) at the Warner Sound show at the Belmont at SXSW.

Charli wrote and appears on the song, but it's the first time that she joined Icona Pop onstage to perform it live. She even talks with us about how excited she was about joining them on stage.

The clip is just 40 seconds in length, but it raises the roof. Everyone is jumping like it's their job. Looks like fun times were had.
