Jessica Chastain, 42, asked the owner of a horse if she could pet it.
"Are we allowed to touch the horse? I don't want to do anything to get you upset", she said — but the horse had bad intentions.
As the horse began sniffing Chastain's blue jacket, it opened its mouth for a quick nibble on the actress' chest.
"Oh! That horse just bit my boob", she said, adding "Alright, I'm not petting you".
