I'm sure that there is a loophole that Kanye wants to test. First off, it's probably not her body and she's going to admit to that. Then there's the fact that he can say the people in the video are doppelgangers. Afterall, which one of them were really there? BTW, the pose is inspired from of a piece of art by Vincent Desiderio.
The desire to stay relevant in Hollywood goes hand in hand with money. They'll both extend each other's 15 seconds of fame if she does...but I'm pretty sure she won't. Not many of these artist control their own careers like people think they do. Sure you can play Devo/Diva, but there is a PR team around you. If her PR team was upset about it...the lawyers would be lined up already.
Hell, there are people who are always looking for a come up..like Ray J (does that really look like RayJ)...but if anyone, I'd expect him (or Amber) to go for the money. Even Cosby is being hush hush...he's got too much going on with his witch hunt. Trump, Brown and a few others have already laughed it off. It wouldn't look good for Taylor to be the only one out of 11 people to sue.
