That didn't take long.
Shortly after we confirmed that 90210 was seeking an actor to play Liam's biological father, the show has found its next recurring star.
As first reported by TV Guide, Scott Patterson has landed this role. The actor is best known for having played Luke on Gilmore Girls from 2000-2007.
Patterson will portray Jack, Liam's real dad, and will appear in multiple episodes when drama returns in January.
