Exclusive: Who's the (New) Boss on Parenthood?

Mark Zuckerberg is headed to NBC's Parenthood... sort of, but not really. Allow me to explain: Anthony Carrigan -- last seen in ABC's presciently titled Christian Slater-led thriller, The Forgotten -- is joining the sophomore drama as Adam's (Peter Krause) new wunderkind-esque boss.

Carrigan's character, Cory, is described as a super-smart and highly opinionated young millionaire who replaces William Baldwin's Gordon as the head honcho at T&S Footwear. Cory -- who made his fortune writing code for flash video games -- sets out to completely reinvent the company.

Michael Ausiello will be contributing to Deadline.com and Movieline.com as he preps for the January launch of a new TV-centric website.
