Gigi Hadid & Joe Jonas Catch the U.S. Open with Kendall Jenner!

Kendall Jenner and Gigi Hadid show their support for the Williams sisters while attending the 2015 U.S. Open on Tuesday (September 8) in New York City.

The ladies were joined at the event by Kendall‘s older sister Kim Kardashian and Gigi‘s boyfriend Joe Jonas, as well as their pal Cully Smoller.

While it will probably be hard for fans of the tennis stars to pick a favorite in the match, we’re going to guess that Kim is rooting for Serena as they were seen grabbing dinner just the night before!
