One Direction ‘What Makes You Beautiful’ on ‘SNL’

British teen idols One Direction continued their U.S. invasion last night as the musical guests on Saturday Night Live. In addition to appearing in a sketch as host Sofia Vergara's five children, Niall, Zayn, Liam, Harry and Louis performed "What Makes You Beautiful" and "One Thing." Both songs are from the group's album Up All Night, which made history in March as the first debut album from a U.K. band to reach Number One on Billboard's Top 200. The boys will be kicking off their North American tour on May 24th in Fairfax, Virginia.
