Adrian Grenier [1] got a head start on his holiday vacation on Friday when he hit the beach in Cancun, Mexico, along with a group of friends. The Entourage star was seen taking a dip in the crystal-blue waters before returning to the sand to do a few push-ups and sit-ups alongside a male pal. The two guys later met up with a bikini-clad woman before heading farther down the beach together. This is hardly the first time that Adrian has hit the beach this year — back in May, the actor showed off his shirtless physique during a trip to Cannes [2]. He has been taking it easy since wrapping up production on the highly anticipated Entourage movie, which is slated to premiere on June 5, 2015.
