2 chainz robbery screenshot*Hmm, maybe now we know why rapper 2 Chainz was trying so hard not to admit that he got robbed in San Francisco  at gunpoint last weekend.

And leave it to TMZ to obtain footage of the event which just happened to have been caught by surveillance cameras. As you’ll see, 2 Chainz doesn’t exactly come off like your stereotypical hard, streetwise rapper. He and his crew got the hell out of Dodge with a quickness when they approached by the bad guys, not that we wouldn’t do anything different. It’s the old fight or flight syndrome that kicked in.

2 Chainz and his entourage were casually walking down the street Sunday afternoon when at least 2 men approached the crew and pointed guns at them … one in a white shirt, the other in a black hoodie.

2 Chainz and his crew immediately scattered — frantically trying to sprint down the street while the gunmen chased after them.

One of the gunmen seemed to be having fun during the incident … and gleefully skipped after the rapper while 2 Chainz tried to get away.

During the chase, 2 Chainz stumbles and falls … and one of the gunmen pounces … hovering over the rapper with his gun drawn.

According to police, the bad guys jacked 2 Chainz for his cell phone and wallet. Towards the end of the video, you can see a man running back up the street with what appears to be the loot stuffed under his clothes.

Under the category: “Who ya gonna believe, me or your lyin’ eyes” … 2 Chainz later posted a tweet denying he was robbed … saying, “Rule #1 if a rapper gets robbed people usually post items that has been taken.”

Yes Mr. 2 Chainz, technically from what can see or not see, it’s impossible to see if the perpertrators took anything from you, but you and your boys didn’t exactly exchange pleasantries with them either

Bottom line: so far no arrests have been made.

Watch it go down:
