The 46 year old was more than a little startled when an unnamed woman sank her teeth into his chest after posing for a photo with him and co-star Michael Rooker at the fan event.

The devotee, who told Reedus she often pretends she's married to the star, was quickly marched out of the Meadowlands Exposition Center and banned from the Walker Stalker Con for life.

The actor has refused to press charges against the woman, who later apologised to her hero via Instagram, revealing her bite never broke the skin - and now Reedus is taking measures to make sure he's never bitten again.

Posting a photo of himself wearing a 'DO NOT BITE ME' T-shirt on Instagram on Tuesday (08Dec15), he added the caption, "Um please don't".
