Taylor Swift and Kendall Jenner illuminated a room together when they hung up Christmas lights at their friend Gigi Hadid's NYC digs Wednesday night.

The model and female love interest of Miguel's "Simple Things" music video captioned the time-lapse video as "First day of snow that sticks means TIME TO PUT UP LIGHTS @emmasittig !!!! Big hugs and candy-cane cookies to our helper-elves @kendalljenner & @taylorswift."

There isn't evidence of these cookies, but what is apparent is that there wasn't any awkwardness between the "Blank Space" singer and the newest Chanel runway model, who both share an ex-boyfriend (*cough* Harry Styles *cough*). As a matter of fact, the two of them are helping each other. Nothing but fun, as Taylor puts it:

To quell any doubts that the two are totally cool with each other, earlier in the day Kendall and supermodel Cara Delevingne, who was also romantically linked to the One Directioner, were spotted leaving Taylor's apartment.

Why can't they all be friends?

Taylor, Kendall, Gigi and her roommate celebrated their hard work with a group hug after they finished decorating the apartment. After all, the holidays are about coming together.

Look at what they all accomplished.

Just de-light-ful, right?
