Vinnie Chases Some Tail

Grenier got wet with a couple of bitches in the surf, then frolicked along the shore a precocious kid and well-bodied blonde. Though Grenier's shirtless chest looked pretty good, it's clear he's no Mark Wahlberg, the muscled former Funky Buncher on whom Adrian's "Entourage" character Vincent Chase is loosely based.

"Entourage" is still shooting ... so maybe he's just chubbing up for some Pablo Escobar re-shoots.
