Myla Sinanaj

Kris Humphries and his on-again girlfriend Myla Sinanaj are so chummy ... the NBA star actually gave Myla his ridiculously expensive Mercedes-Benz -- at least for now.

Kris Humphries and his ex-GF Myla Sinanaj are ONCE AGAIN A COUPLE -- at least that's the way it looked earlier today when the two ventured outside together in public ... and we got the video proof.

Kris Humphries can breathe a sigh of relief -- his ex-girlfriend Myla Sinanaj insists she's NOT PREGNANT ... her belly's just naturally round.

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. Humprhies 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 guys 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.
