Taylor Swift started dating Joe Jonas back in summer 2008, and that relationship fell apart a few months later. Jonas reportedly broke up with Swift in a 27-second phone call and then started dating actress Camilla Belle. Swift was heartbroken and penned the song "Forever and Always" about Jonas, in which she called him a "scared little boy." She also wrote the song "Better Than Revenge," which is believed to be about Belle stealing Jonas away from her.
Taylor Swift met then 17-year-old Taylor Lautner on set for the film "Valentine's Day," and dated from August 2009 until November of that year. It's believed that the song "Back To Decemeber" is Swift's apology to Lautner for their breakup.
