Gigi Hadid has been killing it at New York Fashion Week and her boyfriend Joe Jonas has been in the wings to support her. But recent paparazzi photos show that the person Gigi really loves to turn to is not Joe, but in fact her BFF, Kendall Jenner.

At the US Open earlier this week, Gigi Hadid invited Kendall Jenner along with her and boyfriend Joe Jonas to a game.

But pap photos show Gigi and Kendall whispering and giggling to each other, taking selfies with fans, and all around have a ball of a time - while Joe sat quietly alone watching the game. Awkward.

And at Rihanna's New York Fashion Week after-party, Joe Jonas was photographed with his hand placed on Gigi's neck while trying to talk to her - but her eyes were glued to her phone and she barely even glanced at him.

Maybe she was texting Kendall about the party!

While Gigi and Joe have been dating since June, whenever these two are spotted together they look more like friends enjoying each other's company than two young lovebirds.

But it can't be all bad because a new video went viral today of Gigi singing Joe Jonas' new song - with his band DNCE - "Cake By The Ocean." She was joined by Ciara too. Check out the fun video below:
