Matthew McConaughey was decked out in his usual workout gear and a backpack as he left the Sonya Dakar skin clinic in Beverly Hills today. Matthew recently shaved his head, but he covered up the new look with a gray beanie. He hasn't commented on the decision to lose his blond locks, but he does have a new movie that could be the cause for the drastic change. Matthew is currently filming Thunder Run, but he also has Magic Mike, Mud, and The Paperboy in the works.
It's Matthew six-pack that's getting all the attention, though, in our roundup of the hottest shirtless guys in 2011. If Matthew's at the top of your list, there's still time to vote in our favorite shirtless star of the year poll, which Robert Pattinson is currently dominating.
