Simon Miller has signed on to guest star in two upcoming episodes of the hit series we love, "How to Succeed in Bassness" and "The Grandfather: Part II."

These are the seventh and eighth episodes of the current Season 3.

Miller will play an actor - famous for playing vampires - caught in a triangle between his ex-girlfriend and former co-star, Olivia Burke (recurring guest star Hilary Duff), and Dan Humphrey (Gossip Girl star Penn Badgley).

As an actor, the 25-year-old is best known for appearing in number of independent films, such as Elah & the Moon, Between Love & Goodbye, Pickman's Model, Truth Project, History of Sexuality and others.
