Taylor Swift and Zayn Malik's sultry surprise collaboration for Fifty Shades Darker—dropped just a few days after a brand new trailer for the highly-anticipated BDSM movie—is turning up the heat in a major way and showcasing the artists in fifty shades of sexy.

T-Swift, who has not released any of her own singles since October 2014's highly-acclaimed 1989, showcases a completely new sound in the new track, titled "I Don't Wanna Live Forever," and we're big fans.

"Been sitting eyes wide open behind these four walls, hoping you'd call/ It's just a cruel existence like there's no point hoping at all," Malik croons at the beginning of the single, bringing his trademark sultry vocals that he showed off in his 2016 album Mind of Mine. Swift then takes turns with the former One Directioner on vocals, and the smooth duet is the hit collaboration no one saw coming.

The 26-year-old took to Instagram to tease a snippet of the track as well as the album artwork right before midnight on Thursday, while the 23-year-old Brit said it all with a black-and-white polaroid of him and Swift hanging out while he holds one of her cats in his arms.

The song, which is the first single to be released for the Fifty Shades Darker soundtrack, was written by Swift, Jack Antonoff, and Sam Dew, and it's making us that much more excited for the February 2017 film.
