It all went down at Gigi Hadid's pad in NYC on Wednesday, December 10. She's actually the one who shared the video of the hangout on Instagram.
"First day of snow that sticks means TIME TO PUT UP LIGHTS @emmasittig!!!!" the model captioned the clip. "Big hugs and candy-cane cookies to our helper-elves @kendalljenner & @taylorswift."
In the vid, the girls are seen hanging up lights on a wall and across picture frames. The ladies took turns untangling the string, and hugged it out after their masterpiece was complete. It's kind of surprising considering they've both dated Harry shortly after the other, and there was talk that there was bad blood there.
Check the whole hangout, below. Do you think it was ever awkward for them?
