Dude……..DUDE.

That noise you hear is the sound of Twitter exploding into a million little pieces over the following news: Chris Meloni is being courted to join the cast of True Blood.

TVLine has learned exclusively that the former Law & Order: SVU front man is circling what my sources are calling a “major role” in the show’s upcoming fifth season.

But what role? An HBO rep declined to comment, but I hear Meloni — who’s currently shooting a top-secret role in Man of Steel — is in talks to play (duh) an incredibly powerful vampire.

If a deal comes to pass, this would be a major casting coup for True Blood. It would also mark a high-profile return to the small screen for Meloni following his sudden departure from SVU last spring.
