Is Taylor Swift seeing someone new again, and is he the boyfriend of a Golden Globe Award winner? Well, the answer to that is both a Yes and a No - T. Swift has definitely been seeing Lena Dunham's boyfriend, Jack Antonoff, but not for reasons you might think.

Taylor has just dropped new music this week on iTunes. Her new single "Sweeter Than Fiction" was the song used as one of the soundtracks for the U.K. film, One Chance. So where does Antonoff fit in? Well, Swiftie co-wrote the song with the FUN guitarist and Dunham lover. Thus, Swift and Antonoff have been seeing each other, but just because they were working with each other.

Just like most of the singer's tracks, 'Sweeter Than Fiction' is a love song about "how good it is to be in love," describes Contact Music. The fast-paced pop hit blasts an acoustic guitar with just the right amount of rock; of course, complemented with Taylor's classic sweet voice.

"The distinctly 80s track sees the musical arrangement shift from new wave to pure pop as Taylor takes on the persona of someone who believed in someone else's talent before anyone else did," Contact Music writes.

According to Celebuzz.com, the single will play in the end credits of the film One Chance. The film tackles the story of Paul Potts, an opera singer who auditioned for Britain's Got Talent in 2007 and became a fan-favorite. He went on to win the competition. Contact Music also notes that the coming-the-age film will be making its theatre release this week.

Aside from touring the world with her Red tour crew (including previously rumored boyfriend, Ed Sheeran), Taylor revealed that she has also been working on her new album - something may sound a little bit different than her previous records.

"I think the goal for the next album is to continue to change, and never change in the same way twice. How do I write these figurative diary entries in ways that I've never written them before and to a sonic backdrop that I've never explored before?" she said in her acceptance speech for her Songwriter/ Artist of the Year award from Nashville Songwriters Association, reports Billboard.

One Chance is scheduled to hit U.K. theatres on October 25.
