Guest star.

Cameron Mathison (ex-Ryan) has kept busy since leaving “All My Children” as a “Desperate Housewives” guest star, “Good Morning America” correspondent and host of Dallas Round-Up. Now, he’s headed to “Drop Dead Diva.”

Per The Hollywood Reporter, Mathison will appear in the penultimate episode of “Drop Dead Diva’s” fourth season. He joins Kim Kardashian (Keeping Up With The Kardashians), Nancy Grace (“Nancy Grace”) and Ashley Jones (ex-Bridget, “The Bold and the Beautiful”) in the episode as Jonah Pierce, a charmer who goes on a very bad first date with April Bowlby’s character Stacy.

“Drop Dead Diva,” about a dead shallow wannabe model whose soul ends up in plus-sized attorney, airs on Lifetime at 9:00 PM EST. Mathison’s episode will air in August.
