In a tweet heard around the worlds of teens, pop music fans and gossip mongers, Taylor Swift announced that she was indeed back in the studio. Swift, who put out her massively successful album "Red" in October, doesn't really have any business recording new material. Except for the fact that she's once again newly single.

The 23-year-old is known for lacing her lyrics with digs at her ex-boyfriends, most of whom are quite famous. To date, the singer reportedly counts John Mayer (who's 35), Jake Gyllenhaal (32), Joe Jonas, Cory Monteith, Toby Hemingway, Zac Efron, Eddie Redmayne, Conner Kennedy, Taylor Lautner and a veritable coterie of other actors and musicians among her former lovers. She's dated so many famous blokes that the boys in The Wanted have suggested she might want to just take a break.

It follows, then, that Swift is just letting everyone know she's in the studio writing about her breakup with One Direction heartthrob Harry Styles. Don't worry about Styles, though: He's headed off on a buddy trip with newly outed weed aficionado Justin Bieber. World, carry on.
