Yolanda Hadid has revealed that behind all the glamorous photo shoots and magazine covers, her supermodel daughter, Bella Hadid, is "struggling" with Lyme disease.
The Real Housewives of Beverly Hills star chatted to Good Day New York about her own experience with the infectious disease, which her 17-year-old son, Anwar, and 20-year-old Bella have also contracted.
"Bella is struggling," Yolanda told the show while promoting Thursday's Global Lyme Alliance Dinner in New York. "It's hard to imagine that this beautiful bright light on the cover of magazines could struggle the way that she does."
"She's always tired," Yolanda, 52, added. "She could sleep for 10 hours and wake up [and say], 'I'm still tired.' In the younger generation, it comes up like anxiety, severe exhaustion, joint pain, flu-like symptoms and they just keep struggling over it."
While Bella, who is dating musician The Weeknd, is having a hard time with the disease, Yolanda added that Anwar has the illness under control.
"My son, who has been home with me, is doing great," she shared. "I think he's about 90% and he's very determined to get 100% and he does the work and does what needs to be done."
The disease is caused by bacteria, which is spread through tick bites, and symptoms include fever, joint pain, nausea and rash.
Singer Avril Lavigne previously battled the illness, saying she "thought I was dying."
Yolanda revealed that Bella and Anwar had contracted the disease at last year's Global Lyme Alliance event. Bella is an honoree at this year's gala.
