Regina King

While we anxiously wait for the new season of TNT's critically-acclaimed cop drama, Southland, to premiere next February, one of that show's stars, Regina King, will guest-star in an episode of CBS's comedy hit, The Big Bang Theory, playing the director of employee relations at the university where Jim Parsons' character works, who will "have the unique pleasure of questioning Sheldon after the theoretical physicist lands in hot water following an uncomfortable conversation with his sexy assistant, Alex (Margo Harshman)," says THR.

Apparently, the gues-starring role (which will happen in a January episode) could become a recurring one.

The Big Bang Theory airs Thursdays at 8 pm on CBS.
