As a former successful supermodel, Yolanda Hadid knows a thing or two about the power of promotion.
The Real Housewives of Beverly Hills reality star anticipated the benefits of chronicling her life on camera nearly three years ago when she joined the show, particularly when her two daughters Gigi Hadid and Bella Hadid were just high school modeling hopefuls off of Hollywood's radar.
"At first, Yolanda's children were a big reason she decided to do the show," a source told E! News. "She wanted to boost their careers and she definitely succeeded. Bella and Gigi have become household names."
That fact is undeniable. At just 20 and 19 years old respectively, Gigi and Bella's faces now dominate the fashion scene worldwide, securing major ad campaigns for international brands like Maybelline and Guess, walking the runways of Victoria's Secret and Chanel and appearing on the covers of countless international Vogue magazines.
Even Anwar Hadid, Foster's youngest child, officially launched his own career in front of the camera after posing in the pages of Nylon.
Now that her children are thriving, some may wonder why Foster continues to face the public spotlight on the show despite an debilitating battle with Lyme disease and a very fresh divorce from her husband of four years, David Foster. The simple answer—her sickness is her motivation.
"Now, one of the reasons she remains on the show is to help shine a light on her disease," the source added.
