No matter how big or small your wedding is, one thing you’ll want to keep an eye out for is wedding crashers. Yes, they are real, and no, they aren’t always as fun and entertaining as Vince Vaughn and Owen Wilson were in the movie.
It happens more than you’d think, especially at venues where there are multiple weddings happening in one night, or where the guest count is so high that no one is likely to notice. It's easy for outsiders to sneak in, blend in, and enjoy as much free food and booze as they can before anyone realizes and kicks them out.
But there is one situation in which you might welcome an uninvited guest — and that's when said guest happens to be a major celebrity. Every now and then, whether on purpose or by accident, a star stumbles into a wedding celebration. And sometimes, they stick around long enough for a picture, a dance, or even a Champagne toast.
