Ask most tween girls who is number one on the iTunes charts or who is constantly trending on Twitter and they will say - One Direction.
The band, formed on the UK's X-Factor, is sweeping the globe by storm and now has invaded America.
1D, as their fans refer to them as, recently made a stop in Philadelphia to promote their debut album "Up All Night" featuring the hit song "What Makes You Beautiful."
Niall, Harry, Zayn, Louis, and Liam were able to escape their screaming admirers for a few minutes to chat with 6abc.com.
