Taylor Swift just released her new music video!!

She makes an appearance in her pajamas and telling her ex that they are never going to reunite, no matter what.

It's the first single off her album Red. Taylor's admitted that it's a real-life story about one of her actual exes. But which one? Hmm..let's see. She's already got songs about Taylor Lautner ("Back To December"), John Mayer ("Dear John"), and Joe Jonas ("Better Than Revenge"). It could potentially be about Jake Gyllenhaal, who she dated briefly.

Of course, Taylor could be writing about all of her exes, or even a guy that she dated in secret. Who knows? It's anyone's guess.
