Andrian Grenier Smokes?

Who knew Adrian Grenier was as smoker? 

The out-of-shape actor was spotted lighting up on the set of Entourage with co-stars Kevin Connolly, Kevin Dillon and Jeremy Piven yesterday. 

Though, upon closer inspection I have to wonder if that's actually a cigarette he's smoking and not something else (case in point: he apparently got the munchies a few minutes later.)

Just sayin'...
