EXCLUSIVE: Vanessa Lachey has joined Fox’s six-episode multi-camera comedy series Dads as a regular in a recasting after the project’s table read. Dads, from Ted‘s Alec Sulkin & Wellesley Wild and Seth MacFarlane, centers on two successful guys in their 30s, Eli (Seth Green) and Warner (Tommy Dewey), who have their lives turned upside down when their nightmare dads (Peter Riegert, Martin Mull) unexpectedly move in with them. Lachey will play Camilla, Warner’s (Dewey) wife and, the mother of their two children. She replaces Erin Pineda, who was cast in the role on Monday. In addition to her extensive hosting resume, which includes stints on Entertainment Tonight and Wipeout, Lachey has done acting gigs on such series as Hawaii Five-0, 30 Rock and Psych.
