Bradley Cooper and Jen Aniston: Just Friends?

You know, Jennifer Aniston cannot catch a break when it comes to guys. First, it's the up and down thing with John Mayer (or should I say break up to make up thing?) Then it's this latest rumor with Bradley Cooper.

Then met on the set of He's Just Not That Into You. They flirted at a party. They had dinner. But when asked if the two are dating, he says:

"She's a friend of mine. Simply, simply, just a friend."

Now, they could be trying to keep things quiet until they get more serious. But given Jen's romantic history, I don't think this is the case. So I wonder, WHAT is the deal with these guys she's dating? Or is it her? Does she expect too much from a relationship? Sabotage the thing before it can even get off the ground?

What do you think?
