Who in Hollywood would you date?

I have watched a bunch of vs competitions going on over the past few weeks on who's the hottest, but I'd like to go a bit deeper.

I want to know who in Hollywood you would actually date, if you had the chance. Not just because he/she is good looking, but someone who you genuinely think would make a good boyfriend/girlfriend and possibly husband/wife. Someone you could spend your time with and enjoy.

I find we subject a lot of the Hollywood stars to just appearance, I'd like to see the Hype class it up a bit.

You can pick someone living or dead, doesn't really matter to me. Just a little bit of a description why would be nice.
