The L Word co-star Sarah Shahi has signed on for a one-episode guest spot on Showtime’s Ray Donovan, reuniting with former fictitious fiancee Katherine Moennig. Shahi will play an Armenian pop star named Hasmig, who presumably needs the help of Liev Schreiber’s Hollywood fixer to get her out of a public relations kerfuffle with a well-timed frown. Moennig plays Schreiber’s assistant, Lena (best described, like everyone on Ray Donovan, as long-suffering, especially since the show will be moving into its third season soon.)
