Gigi Hadid delivered a heart-wrenching speech during this week's The Real Housewives of Beverly Hills, honoring her mother's struggle with Lyme disease. "Tonight we're honoring the person that, more than anyone that I know, is hope for Lyme disease awareness: my mom," Hadid said. The short segment is an eye-opening look into the family's dynamic as other members also suffer from the disease. Afterward, her mother, Yolanda, took the stage accepting an award.
