Kanye West Hit Wrong Twin Over Bianca

Last week there were reports that Kanye West was under investigation for punching someone in the face for putting their hands on his wife Bianca [click here if you missed that].

Apparently the alleged culprit was one of a set of identical twin brothers and Kanye punched the wrong one...

From TMZ

Eyewitnesses who were on the scene Wednesday morning at the Chateau Marmont hotel tell TMZ that what Kanye's team said about what happened -- namely, Bianca herself had been assaulted by the man who ran into her -- is totally off base and simply not accurate.

Here's what our sources tell us about how this went down, from their perspective ... a man accidentally bumped into Bianca in the hotel lobby, which they say was busy at the time. We're told it happened quickly, and the man went on about his way.

The guy went outside and sat at a table with friends, and we're told it was at that point Kanye approached them ... to confront the man.

At this point, we're told Kanye punched the guy in the face ... but here's the crazy part -- we're told he actually ended up punching the wrong dude -- because he's a twin and his brother was right there sitting with him as well. So, a mix-up.
