The study was done by Cambridge University researchers, who said that they were able to train sheep to recognise faces of actors Jake Gyllenhaal and Emma Watson, former US President Barack Obama and BBC newsreader Fiona Bruce.
Results said that the sheep were able to spot the right face on more than one occasions.
The BBC quoted researchers as stating that "sheep possess similar face recognition abilities to primates."
The research's lead author Prof Jenny Morton said, "What we did is ask whether a sheep could learn to recognise someone from a photograph."
"We focused on whether or not an animal was capable of processing a two-dimensional object as a person," Morton added.
The study involved eight female Welsh Mountain sheep.
