RUMOR: Is Taylor Swift Dating 'Wish I Was Here' Director/Star Zach Braff?

According to some new rumors, Taylor Swift is reportedly "dating" actor and director Zach Braff. If these rumors are true, this would be pretty devastating for the other Taylor in Braff's life - Taylor Bagley, his former girlfriend!

"Taylor [Swift] and Zach have had a flirty relationship for a while, and [the other] Taylor was always jealous - it was part of the reason they broke up," an insider said, according to Heat. "She and Zach were even posing for selfies and posting them online while Zach and [the other] Taylor were in the process of split up."

The source added: "Zach likes Taylor and is keen to pursue a romance. She's into it, too. They've been hanging out in New York while he's in the play Bullets Over Broadway. He'll head to her TriBeca apartment after the show, and they\re often spotted at Union Square Farmers' Market.

"They like going to see bands at warehouse parties, too. Zach's keen to keep this out of the public eye - he doesn't want to be part of her songwriting - and Taylor says she's ready for something more mature now."

Whether this rumor is true or not, we know of Taylor's longest relationship - with her best friend Selena Gomez! In a recent interview, the singer opened up about her Spring Breakers bestie and explained why their relationship is the longest for both of them.

"It's been the longest one (relationship) I think either of us (has) had really," Taylor revealed about a week after she and Selena proved feud rumors wrong with a Met Gala Instagram video. "When your life changes and you become thrust into this really strange whirlwind, where what your life is is different from what other people think your life is and your life is commented on and your life is written about and fictionalized and all that, both of us have kind of stuck it out and hung in there through all the different changes we've gone through."

She added: "Longevity is something you really can find very precious and rare in friendships."
