CHARLOTTE, N.C. -- Actors Adrian Grenier and Wendell Pierce have both been spotted around Charlotte on Monday. Grenier, of "Entourage" fame, was seen sipping coffee at a Westin hotel, while Pierce, best known as Bunk from "The Wire" and currently starring in "Treme," took in a barbecue sandwich at the Dan the Pig Man food truck at CarolinaFest downtown. An earlier sighting reported by Yeas & Nays--of George Clooney jogging down Tryon Street--appears to be false. A spokesperson for the actor says he is not at the convention.
