Jeff Vespa/WireImage.comElizabeth Reaser is probably best known as New-Face Ava on Grey's Anatomy. But the star of new, much-buzzed CBS show The Ex List may have been called a few other things at the TV Critics party for CBS/CW/Showtime at Boulevard 3 Friday night.
That's because party insiders say Reaser's arrival with Billy Crudup caused consternation for his ex—Weeds star Mary-Louise Parker, with whom Crudup has a child.
Our spies say 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. (Crudup and Parker, you may recall, broke up when she was seven months pregnant with his child in 2003. He soon after was linked to Claire Danes.)
And just in case you needed more drama-rama, Reaser also looked upset and left the party early. Stay tuned.
