Entourage has landed a big guest star for season eight. Or, to be more specific, a Big Bang of a guest star!
Johnny Galecki (below, left), who helps anchor The Big Bang Theory as Leonard, will appear on an episode of this HBO comedy as a version of himself.
As broken by E! News, look for Galecki to be taken on as a client by Eric and Scott. From there, look for things to get awkward when Johnny makes a play for Eric's fiancee, Sloan.
HBO has already confirmed this will be the final season for Entourage. A big screen version of the show is likely to follow.
