Katy Perry got her 15 minutes of fame this weekend … in the wedding crashing world, that is.

Katy stumbled upon a wedding reception Saturday at a Four Seasons Hotel she was staying at in St. Louis — where she was performing the next day. We’re told she asked the bride and groom, Blonie Dudney and Hayley Rosenblum, if they were cool with her crashing for a while.

Perhaps to no one’s surprise … they were.

Eyewitnesses tell us Katy and about 30-40 members of her touring crew joined the wedding guests for some dancing and mingling. Katy mostly hung out with the newlyweds, and was even ramping up to perform for everyone … but pulled the plug when things got a bit rowdy. Although she did stay to take some epic photos.

Sources say Katy stayed for roughly 15 minutes and danced a majority of the time. Some of her entourage hung out a bit longer after she left.

That’s one for the books … and the wedding album.
