Taylor Swift is notorious at this point for mining her personal life and using it as the source material for her much-loved songs. She owns up to that. That propensity caused her to be the butt of Tina Fey's jokes at the 2013 Golden Globe Awards, which lead to some minor (and quickly resolved drama) with actor Michael J. Fox. Since Fey was responsible for stoking the fires, she realizes she is fair game to become the subject of a Swift song -- something she welcomes.
