VIDEO : Demi Lovato Shaves a Dentist's Head While Delivering Singing Telegrams With James Corden

Although we thought singing telegrams died with the movie Clue, it turns out Demi Lovato and James Corden are bringing them back!
The incredible duo dressed the part Tuesday when they drove around Los Angeles delivering their tunes to a few deserving people. Their first stop was to salon Dry Bar where they congratulated Sarah on her recent promotion. Upon finding out that Sarah's favorite type of music is country, Demi put on her best southern accent, which she happened to nail because she's from Texas! Although Sarah and the rest of the customers inside the salon were surprised by the casual celebrity walk-ins, no one could stop laughing once the duo sang their song. They sang, "When it comes to blowin' people, Sarah has no fears."
