Ever wanted to hear Taylor Swift say "yo"? If the answer is yes, then today's your lucky day. Last week at her show in Michigan, the self-proclaimed "nerdy" country-pop singer broke out into an impromptu rap of Eminem's "Lose Yourself" before singing Uncle Kracker's "Smile". 

To be honest, I felt a lil uncomfortable the first time I watched this, but it's definitely growing on me. Yeah Tay's a bit dorky but she can laugh at herself and still pull off a mean Slim Shady verse. Probably the biggest shock though, is how an entire Taylor Swift crowd knows all the words to "Lose Yourself"... Dang, Swift fans got swag.
