Broadway is poised to get a punk rock makeover as Green Day hits Great White Way. "American Idiot," a musical based off the titular Grammy-winning album, makes its debut tonight, and the stars are coming in droves to rock out. Tennis champ Serena Williams told fans, "On my way to @greenday show in Nyc" and "Ugly Betty" actor Michael Urie posted, "going to the American Idiot opening night - SO excited!" But, no one was more excited than the show's cast, including its star John Gallagher, Jr., who posted, "Cast album, Drama League Nominations, opening night. It's all a bit overwhelming! Thanks to those who made these things possible. Gratitude."
As Broadway tackles a new frontier, "The Vampire Diaries" and "Lost" star Ian Somerhalder has once again found himself in the pages of a magazine. Ian told fans, " the wonderful people at GQ were crazy enough to put me in their magazine and it just came out. Go check it and maybe just maybe they will think people actually like me:)" No maybes necessary, Ian! We like you. We really like you.
