Katy Perry & John Mayer strip club extravaganza: 'Dark Horse' beauty and boyfriend drop thousands on sexy strippers after Super Bowl (PHOTOS)

It's no secret that Katy Perry and John Mayer are involved in a rather "serious" romantic relationship. But apparently, the adorable couple doesn't mind sharing the love!

According to TMZ, the "Dark Horse" songstress and her new boy toy "made it rain" (in the thousands) on some sexy strippers after the Super Bowl on Sunday evening (Feb. 2).

Perry and Mayer stopped by the Spearmint Rhino strip club in Santa Barbara around 11pm that night after the Seattle Seahawks totally pulverized the Denver Broncos. Insiders claim that they spent thousands of dollars, tipping the sexy dancers lavishly and even sitting for several private strip teases.

Hot.

Well it's true... Katy Perry kissed a girl, and she liked it. And here are the Instagram photos to prove it.

Are Mstars fans jealous, or could they have found some hotter chicks?
