The social media jab also took aim at the company's who work with them -- Bella models for Nike and Kylie is the face of Puma.
Meryl, an Olympic figure skater, posted a side by side photo of Bella, Kylie and gold-winning Olympian gymnast Alexandra Raisman, who promotes Reebok Women. Meryl captioned it, "I'll take the one promoted by the athlete please 💪."
Reebok Women seemingly backed her up, tweeted a hands emoji as if to say thank you.
Bella's mom, Yolanda Hadid didn't take to kindly to the slam and also said it wasn't accurate either.
The former "Real Housewives of Beverly Hills" star told TMZ Bella had athletic dreams and was well on her way to being an Olympic equestrian, saying she competed in equestrian by riding every weekend from age 3 until 15, until the model was diagnosed with Lyme disease. Side effects include fatigue and slow reaction times, something not exactly conducive with competitive horseback riding.
Bella was forced to quit riding competitively because of Lyme Disease, said Yolanda, who also suffers from the illness.
"You obviously don't have to be an athlete to wear or enjoy Nike wear," Bella and Gigi Hadid's mom said.
Yolanda was diagnosed with Lyme in 2012. Last year, she revealed that her daughter Bella and son Anwar were also affected.
"When my two youngest children, Bella and Anwar, were diagnosed with chronic Lyme disease in early 2012, watching my babies struggle in silence in order to support me in my journey, struck the deepest core of hopelessness inside of me," the mother of three said during a speech at the Global Lyme Alliance inaugural gala in New York, where she accepted the "Power of One" award.
She dedicated her honor to her kids.
"This award is for Anwar and Bella.. This is my token and my promise to you that I will not allow you to live a life of pain and suffering," she promised. "I will walk to the end of the earth to find a cure so that you can live a healthy life that you deserve. No child should suffer the way that you do."
