Charli XCX was the musical guest on last night's episode of "Saturday Night Live". Martin Freeman hosted. Joined by an all-female band wearing matching suits and ties, she did her Sucker singles "Boom Clap" and "Break the Rules". Prior to the performance, she told MTV that she was so nervous for the appearance that she "might vomit". (Fortunately, she didn't.) Watch it below.
