More guest stars will be making their way over to CBS' hit crime series, Criminal Minds, as Royal Pains standout Paul Costanzo is the latest to be gracing the program.

According to The Hollywood Reporter, the actor is set to don a role in episode 12 in Penelope Garcia's (Kirsten Vangsness) prior checkered past before she went on to become a tech brainiac of the BAU squad.

There has also been chatter that Scandal actress Bellamy Young may be returning to reprise her role as Beth, Hotch's (Thomas Gibson) love interest, in the fifth installment of season 9.

Gibson had previously spoken to TVLine on Oct. 29 about the prospect of Young coming back on board to work with him, which he says is up to Scandal creator Shonda Rhimes.

"It's all up to Shonda. It'd be nice to see if she'd let [Bellamy Young] come and play. I'm hoping that they will," he said.

CBS' Criminal Minds will be airing its next episode, Gatekeeper, on Wednesday, Nov. 6 at 9/8 p.m. Central Time. Be sure to keep checking back for more information on the popular TV series. A promo video for the upcoming installment can be viewed below.
