Can you guess which hawt Hollywood actor has become the latest male celeb to get on board with the new facial hair trend?

This guy enjoys fame on the small screen but not on network TV. Additionally, he set tongues wagging when it was discovered that he is dating his on-screen sister in real life. After the jump, find out who it is and check out more pics of this guy’s new ‘stached look …

It’s Michael C. Hall — Showtime‘s Dexter:

I’m not exactly sure how I feel about this new look for Mr. Hall. I’m afraid he looks a little too much like Robin Hood to me … mebbe if he shaved off the soul patch he’d look better? You will note that Michael is standing next to Jennifer Carpenter (who plays his foul-mouthed sister Deb on Dexter) … I’m glad to see that they’re still together. I wonder what she really thinks about his new look. Mebbe it’s for a new role, mebbe it’s just for fun but I don’t think I want him to keep it for long. This is a look I’m not really loving just yet. Do any of y’all like it?
