John Corbett is reprising his role as Lauren Graham's ex on 'Parenthood' this season. The former 'Sex and the City' stud will drop into town for several episodes as Seth, the alcoholic father of Sarah's character.

"Just when everything seems to be going well between Sarah and Mark [Jason Ritter], Seth shows up and he's kind of in a darker place than he's been," creator Jason Katims told TVLine. "And so you see Sarah really having to struggle with wanting to help him and be there for him, but also at the same time [be fully present] in this relationship with Mark that's really good and healthy."

Also going on in the Braverman world: Brittany Belt will play Haddie's BFF who disapproves of her relationship with Alex, TVLine reports.
