Are Taylor and Sam BFFs?

From singers, to actors, to models, Taylor Swift has the coolest clique of buds in Hollywood, and her latest BFF is "I'm Not the Only One" singer Sam Smith! Taylor even recalls the first moment that they formed their bond at last year's American Music Awards. "We were front row watching Ariana Grande, loving her performance," Tay describes. "At the end of her performance, she did some dance that was so cool, and at the same time, Sam and I both screamed out, 'YAS,YAS!!" and then looked at each other and died laughing. I had this feeling that we'll be friends for life."
