Have you ever done a double take at dinner, the grocery store or on the street convinced the person you've just spotted is someone famous? It happens to everyone from time to time, including HLN's own Lynn Berry! Her look-alike? Cobie Smulders, also known as Robin from the hit show "How I Met Your Mother."
Weekend Express challenged viewers to share photos of their celebrity look-alikes and they delivered big time. Do you or someone you know look like a celeb? Share your photo on our Facebook page or tweet it at us using the hashtag #HLNlookalike.
