Generally, wedding crashers are dreaded rather than welcomed. No matter how big or small your wedding is, one thing you’d rather not want to see is wedding crashers... unless the person happens to be a major celebrity.

Every now and then, whether on purpose or by chance, a celeb stumbles into a wedding celebration. And most of the times, these celebrity wedding crashers stick around long enough for a photo, a dance, or even a Champagne toast with the couple.

Here, all the celebrities who have shown up, without an invite, to ceremonies and receptions—making these couples' special days even more memorable.
