Sources confirm to me exclusively that Kevin Alejandro—a.k.a. Lafayette’s current squeeze, Jesus, on True Blood—is joining the NBC drama for a multi-episode arc as a possible love interest for Graham’s Sarah. Alejandro will have to duke it out with Billy Baldwin, who, as I reported last month, is also coming on board as a suitor for Sarah.

Alejandro’s character, Mike, is described as a blue-collar type who works in the warehouse at Adam’s company—where Sarah is now employed as well. The added wrinkle? Baldwin’s character works there, too as Adam’s boss.

In other Parenthood casting news, Zosia Mamet (United States of Tara‘s Courtney) has been tapped to play the recurring role of Kelsey, Amber’s moneyed new BFF. “She comes from an upper-crust kind of background,” exec producer Jason Katims recently explained. “It becomes complicated for Sarah because Amber’s suddenly being taken into this world that’s out of her grasp.”

Parenthood‘s second season kicks off on Sept. 14.
