Was it just too cute to be true? After just three months of dating, Swift and Taylor Lautnercalled it quits in late December of last year. Sources said that the Twilight star, who flew to Nashville to celebrate Swift's 20th birthday, was more invested in the relationship. The country singer parted ways with him just a few weeks later. True to form, Swift used Lautner as inspiration for one of the song's on her new album. In "Back to December" she apologizes for ending their romance: "This is me swallowing my pride, standing in front of you saying I'm sorry for that night. And I go back to December all the time."
