CELEB REFRESH: Yolanda Hadid’s Bare Ass is Tight, Right, and Outta Sight

So, 52-year old mother of supermodels Gigi and Bella Hadid is the living definition of “shaking what your momma gave you” this weekend.

The supermodel-maker showed her assets in a new Instagram photo in a stunning shot taken during a visit to Lake Constance. “It’s a beautiful, mystical sunrise at the lake this morning,” she wrote.

The Real Housewives of Beverly Hills alum has been battling Lyme disease since 2012, and said the lake is helping to improve her health. “The water is quite cold but it has been a great way to combat inflammation and feel the connection to Mother Earth,” she wrote. “#LakeConstance #MorningSwim #HealingPower #LovingLife.”
