Sam Smith Had to Cancel a Performance Because His Voice Is Gone

International treasure Sam Smith had to pull out of the Capital Summertime Ball in London at the last minute because he lost his voice. The singer apologized in a Facebook post yesterday writing, "This is the first show I've ever had to cancel and I am praying that it is the last. I really have to avoid any long term damage to my voice." Get well soon, Sam! We need you to sing more Whitney Houston classics!
