Watch Charli XCX play "Boom Clap" and "Doing It" on Jimmy Kimmel

She performed "Doing It", her single with Rita Ora (though Ora's absent), and The Fault In Our Stars track, "Boom Clap".

XCX appears to be digging the cowboy vibes, with cutouts of cacti, boots and a bizarre looking bovine benig onstage. She's also dressed in leopard-print chaps, avec matching stetson, and her band look like something from Roadhouse.

Sucker is released 16 February on Asylum; it's out now in the States.

You can see the performances below.
