Lea Michele and John Stamos Grill Taylor Lautner About His Ex Taylor Swift

Lea Michele: actress slash investigative journalist? On Monday, the Scream Queens actress joined her co-stars Taylor Lautner and John Stamos, for a Facebook Live Q&A to preview the new season of Fox’s hit show, but when the conversation turned toward the Twilight star’s dating history, Lea was quick to bring up his famous ex Taylor Swift.

The two Taylors briefly dated after meeting on the set of the rom-com Valentine’s Day, and it has long been rumored that the Grammy winner’s 2010 ballad “Back to December” is about their romance.

“Didn’t she write a song about you?” Lea asked Taylor. “That’s what she does,” he responded, looking visibly uncomfortable. “She writes songs.” After confessing to be a Swiftie herself, Lea couldn’t remember the title or the lyrics to the tune. “Something about, ‘If I would have known / I wouldn’t have done that / I’ll make you a hat,’” she said. “Something about a hat! I don’t know!”

While she butchered the words to the song, she had Taylor backed into a corner. “It’s called ‘Back to December,’” he said with a coy smile.
