When you're Gigi Hadid, you stay busy grinding out fashion shows and appearances like whoa. However, everyone needs a little break for the holidays and that includes Halloween. The 21 year old model made an appearance on Today's Wednesday episode to discuss how her spooky night went. "Halloween was really cool. We were all working, so my friend had just a little girl's night at her house," Hadid dished. Turns out that friend was none other than pop singer Taylor Swift.
