Billy Crudup and Mary-Louise Parker have been split up since 2003.  You might recall that he left her, knocked up with his child, for Claire Danes of all people.  (That's definitely a downgrade as far as I'm concerned, but this story isn't about that.)  If E! Online's spies are to be believed, Parker may still have some unresolved feelings.  When he showed up at a CBS party with his date

Parker was visibly upset in the back corner of a cabana, as she talked with co-star Justin Kirk. She ultimately wobbled out of the party with her hair mostly hiding her face and her hands on a companion's shoulders to steady her.

Um, that sounds more drunk than upset to me, or maybe Parker was sampling a bit of her Weeds character's product? 

But who was Crudup with that upset Parker so much?  None other than Elizabeth Reaser.  If you are currently wondering who the heck Elizabeth Reaser is, you're in good company - namely me.  She's Crazy Eva from Grey's Anatomy!  I watch that show religiously and I didn't know Eva's real life name; I can't say that I've ever paid that much attention to the credits.   

Reaser is starring in CBS' new show The Ex List this fall.  I guess that probably means we won't see her anymore on Grey's.  Not that the season finale left much hope of that, but until she went bonkers, I liked her a lot.  Not crazy, she's certainly better for Alex Karev than Izzie Stevens or that little nurse.   Whoops, now I'm on a Grey's tangent... can you tell I'm in withdrawal?
