It's not every day you get married, and it's not every day a celebrity crashes your party.
But that's what happened to a local newlywed couple at the Four Seasons.
Bride Hayley Rosenblum and Groom Blonie Dudney were celebrating when Katy Perry came in to party.
Their guests said Perry came at the end of the reception and danced with the guests for about 10 minutes.
Perry played at the Scottrade Center Sunday.
