We've done our due diligence, and here's what we found.  First, the woman in the pic appears to be porn star Amia Miley. Miley tweeted the same photo of herself on her twitter account in 2011, and she tells us it's her. She also says she's never hooked up with Kanye.

Second, although the pic has been sent around with credit to Kanye, we've learned it was never posted on Kanye's account. A source close to Kanye confirms ... he didn't do it.

We're told it's all part of #WanksterWednesday -- a prank day where people try to get bogus rumors started.
