If you needed two more reasons to catch ABC's unquestionably entertaining Samantha Who?, here they are: Sources confirm to me exclusively that producers have tapped ex- Invasion hottie Eddie Cibrian and short-lived Lost castaway Kiele Sanchez for multi-episode arcs.

Cibrian has been cast as a love interest for Christina Applegate's title character, while Sanchez - who I swear is just one good role away from being a huge star - will romance Barry Watson's Todd.

ABC is clearly looking to keep both actors on the payroll. In addition to their respective roles on Invasion and Lost, Cibrian and Sanchez starred in the Alphabet Net's ill-fated Football Wives pilot.

Samantha Who? premieres on Oct. 15 and, trust me, you guys are gonna Eat. It. Up.
