‘Royal Pains” Mark Feuerstein + ‘The Walking Dead’s’ Andrew Lincoln — Dead Ringers?

SPOILER ALERT! We've got a huge insider secret to share about 'The Walking Dead,' and we're not talking about the surprise return of a certain season 1 character. Intense photo research has confirmed that Andrew Lincoln, the star of the AMC series, is in fact Mark Feuerstein from USA's 'Royal Pains.'

Just kidding, but both guys could definitely be each other's separated-at-birth twin brother. The resemblance is uncanny, especially when the pair starts to get the five o'clock shadow. Would you be able to tell the difference if all of sudden Feuerstein switched to shooting zombies and Lincoln was busy attending to rich people's paper cuts?
