Taylor Swift's new 1989 song "Out of the Woods" is officially, well, out of the woodwork and the ambitious new pop single just oozes of her collaborator and co-writer Jack Antonoff of Bleachers and fun. fame. After the song's successful debut last night (Oct. 13) just before the strike of midnight, Antonoff, Swift and Antonoff's girlfriend/Swift's bestie Lena Dunham are all praising the track to high heavens on Twitter and Instagram.

Shortly after "Out of the Woods," the layered, throwback pop anthem that is probably about Swift's bumpy relationship with One Direction heartthrob Harry Styles, Dunham showed off a behind-the-scenes photo of the first time Antonoff and Swift collaborated on new music.

In Antonoff and Dunham's living room, Swift can be seen wearing some brown shorts and a greay sweater as she looks over the producer/songwriter Antonoff, who is hard at work on the computer.

The snapshot from the 1989 recording sessions is just a small sampling of the love between Antonoff and Swift on social media, as the musical duo gushed about each other and "Out of the Woods" following the song's release.

Antonoff reflected on his production work on "Out of the Woods," emphasizing how much he loved working with Swift on Instagram. "will one day write an essay on the different production I used on the song + how much working with taylor on it has meant to me. she's a wonderful artist," he wrote.

Meanwhile, Swift herself freaked out about the song's successes on Twitter, after finding out how to download the track from iTunes in the first place, with some help from Antonoff.
