Zac Efron was all smiles on Sunday (15Dec13) as he helped members of American football team the Indianapolis Colts celebrate their win against the Houston Texans, weeks after breaking his jaw. Last month (Nov13), the Hairspray star was forced to have his jaw wired shut after reportedly slipping in a puddle at his Los Angeles home and badly smashing his face. But now the 26-year-old hunk is back to flashing his pearly whites after travelling to Indianapolis, Indiana as a guest of the football team. Efron took to Twitter.com to post a photo of himself grinning from ear-to-ear and giving a thumbs up alongside team owner Jim Irsay, and donning a blue and white Colts santa hat, as the two enjoyed the game from a private box. He added the caption, "Thanks Jim for a truly memorable trip to Indie (Indianapolis). Congrats on the win, @Colts!" Colts player Matt Overton also posed with the actor after the game, and posted a photo with Efron in the locker room at Lucas Oil Stadium, alongside the caption, "Winning feels so damn good! Zac Efron came to party too."
