John Travolta was in Georgia renewing his pilot's license. And he happened to meet a young couple at a bar, the night before their big day. The big movie star surprised the engaged pair the next day when he crashed the nuptials! John was reportedly a sweetheart and took pics with the bride and groom, and their entire bridal party! No word on if John will be flying the newlyweds to their honeymoon destination, but this is one big fat 'Grease' wedding the couple will be telling their kids and grandkids about!.
