It’s a ZBZ/Kappa Tau reunion — and in a most unlikely place.

TVLine has learned exclusively that Greek alumni Spencer Grammer and Aaron Hill have both landed guest-starring roles in the same episode of CSI: NY.

The former co-stars will appear on the CBS cop drama as techs in Mac’s lab who are questioned when one of their coworkers is found murdered in a manner reminiscent of a 1950s cold case.

Grammer and Hill played pledge pals for four years on Greek, ABC Family’s college comedy, which concluded its run last March.

CSI: NY resumes Season 8 on Friday, Jan. 6, with the Grammer/Hill episode set to air sometime in the spring.
