'Dexter' Season 8 Photos: Jennifer Carpenter On Set

Filming for "Dexter" Season 8 is already underway as Showtime's serial killer thriller approaches its an earlier-than-usual June premiere date. And judging from some new images from the set (courtesy of Spoiler TV) , Deb is spending time with a new guy who many fans believe to be Rhys Coiro, a familiar face to premium cable viewers.

In the images below, Deb (Jennifer Carpenter) -- sporting some unusually wavy hair -- can be seen hanging out with the man that could be Coiro, who "Entourage" fans may recognize as the mercurial director Billy Walsh.

Showtime has not yet announced Coiro's casting, but the network has revealed that Sean Patrick Flannery and Charlotte Rampling are joining the upcoming eighth season of "Dexter." Coiro recently joined Jerry Bruckheimer's "Hostages" pilot, which is in development at CBS.

UPDATE: THR confirmed that Rhys Coiro has indeed been cast in "Dexter's" upcoming season. He will play a "tough bail jumper that Deb is tracking" in a one-episode guest spot.

"Dexter" Season 8 premieres in June on Showtime.
