Hollywood - Ellen DeGeneres' intro description for Zac Efron, "Our first guest is the biggest teen heartthrob in the world, the world!", then the crown screamed like crazy lunatics. April 15 when 17 Again star Zac graced the popular talkshow. "This is a great crowd, thank you." says Zac, after hearing the nonstop screams of live audiences. Ellen asked Zac if he's not used to bunch of girls screaming when he's around. "No, its a great noise - thank you everybody, its very sweet." he answered, then the crowd went gaga again. The High School Musical alum talks about how cool the SNL hosting week was, "Oh man, it was a crazy week. It really was just amazing." says Zac. Spoofing his own movie in the popular American gagshow was fun to watch, very hilarious.
