Charli XCX was featured as the musical guest on the most recent episode of “Saturday Night Live,” in promotion of her sophomore album, “Sucker.” The singer performed tracks “Boom Clap” and “Break the Rules” off the album, which drops on Tuesday. Backed by an all-female band dressed to the nines in suits and red lipstick, Charli opened up with her “Fault in Our Stars” hit, keeping her spicy attitude relatively low-key. However, during her anti-school anthem, Charli upped the energy as she broke out some dance moves, matching her “nah nah nah’s” with some big hip thrusts. Watch both performances above and below.
