Kris Humphries -- I Can Make You Famous, Bro

Kris Humphries believes he's the next Kim Kardashian -- as in, dude believes he wields the power to make someone famous with the snap of his finger ... and last night, he tried to prove it.

Humphries was leaving AV nightclub in Hollywood around 2 AM ... when we asked him about the baby mama drama in his life. But Kris wasn't in the mood to discuss parenthood ... instead, he promised to "blow up" our photog (in a good way) by taking his pic and posting it to Twitter.

Kris -- who was very nice BTW -- took our guy's pic and was ready to tweet at him ... but there was one really big problem ... you can't tweet at a guy who doesn't have a Twitter. Bummer.
