While Lost fans are excited about the rumored return of Cynthia Watros to the show this season, the actress likely won't reprise her role as Libby for very long.

That's because she's landed a new gig on another network, signing on for multiple episodes of House.

Insiders have confirmed to Michael Ausiello that Watros has been cast as Wilson’s ex-wife (his first of three, that is). She's poised to re-enter the doctor's life... as his new girlfriend!

The actress will debut in April. Her character's relationship with Wilson will mark his first romantic entanglement since Amber died two years ago.
