After breaking up with Harry Styles right on schedule, Taylor Swift is already recording a song about it. We're sure his One Direction bandmates are thrilled.

Swift tweeted cryptically about it, because that's her thing now:

At least John Mayer can breathe a sigh of relief after this one.

Swift was reportedly not that nice to Styles while they were together, which is odd, considering her reputation as a stage five clinger. The Sun reports that during their "great row" in the Virgin Isles, she told him, “You’re lucky to even be with me.”

Oh, really? Do Jake Gyllenhaal, Joe Jonas, Eddie Redmayne, Conor Kennedy and God knows who else agree? It's not like Styles is a slouch -- he's the token heartthrob of the biggest boy band on the planet. This pairing was, at worst, a lateral move for them both.

“Taylor knows she’s far more high-profile in America and way richer, and saw her career as more important," a source close to the couple told The Sun. "She always brushed off his schedule and needs and put hers first. When he complained his bandmates were getting irritated and she should do more to make things work, they started to yell crazy things."

There was also the usual issue with Swift's relationships: Notorious ladies' man Hazza wasn't ready to put a ring on it. “There were also problems over commitment," the source added. "Harry wasn't committed enough for her liking.”

Here's hoping she gets all of her vitriol out in a song that will be inevitably overplayed -- and that Styles doesn't have a pet bunny. Otherwise he (and it) may be in hot water.
