One Direction On 'Saturday Night Live': Boy Band Makes 'SNL' Debut (VIDEO)

Teen girls across the U.S. stayed up all night to watch British boy band One Direction make their "Saturday Night Live" debut.

In case you haven't heard, One Direction -- comprised of Zayn Malik, Harry Styles, Louis Tomlinson, Liam Payne and Niall Horan -- is currently taking over stateside with teen girls across the U.S. falling for their British charms. Even "SNL" host Sofia Vergara couldn't resist getting excited over the boys' performance.

One Direction -- dressed in their post-prom best -- performed two songs off their debut album, Up All Night, and it seemed as if the boys were singing over a pre-recorded track for part of their performance. However, their screaming fans didn't seem to mind.

The album made history when it debuted on the charts with 176,000 units sold, according to Nielsen SoundScan. One Direction bested the previous record set by pop group the Spice Girls in 1997 when their debut album "Spice" entered the charts at No. 6.

Recently, One Direction was caught in the studio with Justin Bieber. However, the band is denying a collaboration with Bieber at this time.

The five young chaps will also be hitting the road for their first headlining North American tour in support of their album Up All Night. The tour will kick off in Fairfax, Va., on May 24 and includes stops in New York City, Los Angeles, Toronto, Dallas and more.

To add to their stateside success, One Direction just landed their own Nickelodeon show. However, despite the network's statement, the band has yet to confirm that there will be a Nickelodeon show.
