Charli XCX performs during Jimmy Kimmel Live on Feb. 3, 2015 in Los Angeles, California.

When it comes to late night TV performances, this ain't Charli XCX's first rodeo. But she still showed up to Jimmy Kimmel Live! last night (Feb. 4) like a new sheriff in town.

Or something like that. Dressed in leopard print gaucho cowboy pants, Charli delivered "Doing It" from her 2014 album, Sucker, which up until now had absolutely nothing to do with the Wild West. Check out the video below, as Charlotte performs with a few extra backup singers added to her new wave-y live band:

Next up, the cardboard cacti, cow and boots were cleared aside for a performance of her hit single, "Boom Clap":

"Boom Clap" went all the way to No. 8 on the Billboard Hot 100, Charli's highest hit yet as a lead artist.
