Starting tonight, a couple of fresh faces will appear on Lie to Me.

Jennifer Beals (The L Word) shows up as Cal Lightman's ex-wife, while former ER star and Mekhi Phifer joins the series as a regular on May 6.

Monica Raymund, who plays Ria Torres on the series, spoke to TV Guide about each of these stars.

On Jennifer Beals' character: Her character is definitely a well-to-do, successful and independent woman. She doesn't need Cal's approval or judgment on anything, she's her own woman.

On Mekhi Phifer: He's awesome. Such a great actor, a great man and lot of fun to work with. I was a big fan of his when I met him, so I was a little star-struck. I was like, "What was it like working with Eminem [in 8 Mile]?"
