'Meet my twin stranger'

Looking in the mirror or identical twins? No, we are strangers.

Niamh Geaney, 26, from Dublin, Ireland found a complete stranger looking remarkably like her from a worldwide search and the doppelgänger turned out to be a fellow Irish woman, Karen Branigan, 29, who lives an hour down the road from her.

Geaney and two of her fellow college mates launched the challenge as a social experiment and all three have received photos from potential look-alikes across the world.

Geaney found the closest match.
