Lie to Me

As previously reported, Mekhi Phifer will be a series regular next season on Lie to Me.

He'll be joined by Jennifer Beals, who won't be a full-time cast member, but will often recur as Cal Lightman's ex-wife.

Meanwhile, Entertainment Weekly reports that some new blood is coming to the Fox show: viewers will meet Lightman's longtime rival, an expert in the same field. The role has not yet been cast.
