Some of Paris Hilton's ex-boyfriends are so obviously gay ... it's shocking she hadn't heard of Grindr before her recent AIDS rant -- this according to the makers of the gay phone app.
Grindr tweeted at Paris moments ago, writing, "Frankly, we're surprised that you hadn't heard about Grindr sooner, given some of the guys you date."
Grindr then links to the above photo of Paris and her ex-boyfriend Doug Reinhardt from a 2009 costume party, where Doug is dressed like a fairy.
(Okay, that's pretty funny.)
You'll recall, Paris was speaking about Grindr when she said, "Gay guys are the horniest people in the world ... they're disgusting. Dude, most of them probably have AIDS."
