Meghan Trainor hasn't had the easiest week. The pop star pulled her music video for "Me Too" after photoshopping controversy blew up. Then, she took a tumble (like a pro) on The Tonight Show. Fortunately, the Billboard Music Awards are going pretty well for Trainor so far. In a red-carpet interview before the show, Trainor learned that a huge star is a huge fan of her own song, "No." Hearing the news brought her to the brink of tears. "My eyes are very watery!" she said.
