Hadid - who is battling Lyme disease - has been serving up inspiration on her Instagram account all week.
Hadid made headlines recently after divorcing husband David Foster.
A statement released to PEOPLE read: "Sadly we have decided to go our separate ways. We've shared nine beautiful and joyous years together.
"During that time we experienced love, friendship and the inevitable challenges that come with managing a marriage, careers, blended families and health issues."
