As far as parental cliffhangers go, it’s second only to the identity of the Mother on a certain CBS sitcom: Glee has finally cast Rachel’s gay dads, and TVLine can reveal which musically-inclined actors landed the plum parts.

A show insider confirms to TVLine exclusively that onetime Law & Order: Criminal Intent detective Jeff Goldblum and Broadway veteran Brian Stokes Mitchell have been tapped to play Hiram and LeRoy Berry, the adoptive parents of Lea Michele’s character.

The duo will first appear in the show’s Valentine’s Day episode — which as luck would have it will actually air on Feb. 14, and is titled “Heart.” And yes, they will sing.

Although Goldblum is best known for his movie and TV work, he’s also an accomplished jazz pianist who made his Broadway debut back in 1971 in the Tony-winning musical Two Gentleman in Verona.

Mitchell, meanwhile, is something of a Great White Way legend, having appeared in dozens of high-profile productions including Jelly’s Last Jam, Ragtime, Man of La Macha and Kiss Me Kate (for which he won a 2000 Tony Award for Best Actor.) His TV credits include playing Kelsey Grammer’s onscreen nemesis on Frasier and a love interest for Vanessa Williams’ Wilhelmina on Ugly Betty.
