During Thursday's episode of "The Talk" host Julie Chen tries to shave her eyebrow to prove she's a true "Puthinator," but is stopped short when singer-songwriter Charlie Puth himself makes a surprise appearance. Puth says, "I'm flattered, but don't do that... I had to run into 'The Talk,' bypass all of the security to stop you." Sara Gilbert asks Puth if his signature eyebrow look was from a scar. Puth replies, "When I was 2 years-old a dog bit my face," and admits, "It is super flattering that fans will shave their eyebrows for me."
