Taylor Swift Sings to ex Calvin Harris' song at NYFW

Pop star Taylor Swift surprised many when she was heard cheerfully singing to her former boyfriend DJ Calvin Harris's track "This Is What You Came For" while attending the New York Fashion Week.
On September 9, Swift, who recently split from actor Tom Hiddleston, attended Tommy Hilfiger show during NYFW to support best friend Gigi Hadid, who presented her special collection in collaboration with the famous fashion brand, reported Aceshowbiz.
The 26-year-old singer/songwriter sat front row next to model Martha Hunt.
In a video she posted on Instagram, the "I Knew You Were Trouble" songstress was cheerfully singing to Harris and Rihanna's song "This Is What You Came For" which was played when the models walked the runway.

"SO PROUD OF YOU GIGI!!!! That show was INSANE. Congrats to Gi, Tommy, and all the girls who just owned that runway!!" she wrote in the caption of the video.
Gigi's mom Yolanda Hadid and brother Anwar Hadid as well as Kris Jenner, Doutzen Kroes and Olivia Palermo were among other attendees at the TOMMYxGiGi fashion show.
Swift was initially credited under the pseudonym Nils Sjoberg on "This Is What You Came For". It's not until after their split that it was revealed she co-wrote the catchy track. The credit has since been changed to "Taylor Swift" in Broadcast Music Inc's entry for the song.
