They may have had a public spat about who wrote his summer smash.
But Taylor Swift seems to have no hard feelings towards her ex Calvin Harris and was seen singing along to his song, This Is What You Came For, at New York Fashion Week on Friday.
Not only did she happily chirp along to the hit that she co-wrote, she filmed herself doing it and then POSTED it on her own Instagram page.
That show was INSANE. Congrats to Gi, Tommy, and all the girls who just owned that runway.
It was just another way for the 26-year-old to support her girl squad member, supermodel Gigi Hadid, who Taylor filmed strutting the runway at the Tommy Hilfiger show.
The Shake It Off singer posted the clip on Instagram and wrote: “SO PROUD OF YOU GIGI!!!!
“That show was INSANE. Congrats to Gi, Tommy, and all the girls who just owned that runway!!”
In July a rep for Taylor revealed that the star secretly co-wrote This Is What You Came For, which was a hit for Calvin Harris and featured Rihanna on vocals.
The Scottish DJ fired back on Twitter: “Hurtful to me at this point that her and her team would go so far out of their way to try and make ME look bad at this stage though.”
But Taylor clearly has put the row behind her.
In the Instagram clip she’s “oohing” and “ahhing” along to the backing vocals with her model pal Martha Hunt.
They both also shared a photo of themselves with the singer showing her mate something on her mobile phone.
Martha, 27, wrote next to it on her page: “Tinder. Jk chill.”
But Taylor said on Instagram: “Looking up videos of kittens hugging each other, probably.”
