Yolanda Hadid of the Beverly Hills-based installment of Bravo's "The Real Housewives" has taken on her ex-husband Mohamed Hadid's last name. This leads to speculations that they are getting back together.

After filing for divorce from husband David Foster weeks ago, the reality star and mother of three revealed to Andy Cohen during an airing of his talk show, “Watch What Happens Live,” that she would be dropping Foster from her name, and taking on Hadid. However, according to Yolanda, she and Mohamed aren't getting back together. Instead, they are simply doing what is best for their children.

“You know when you divorce, when you have children with somebody, you put your ego aside. This is not about how I feel about my ex-husband," Foster told The Daily Dish of her relationship with Mohamed. "This is about how my children feel, how Mohamed and I make our children feel, because at the end of the day it’s about them.” 

Yolanda and Mohamed tied the knot in 1994 and in 2000, after welcoming three children together, Gigi, Bella and Anwar, they parted ways. Then, in 2011, Yolanda married Foster, and the two parted ways last year.

Aside from her recent divorce announcement, Yolanda has also been going through hard times with her health. In 2012, just a short time after marrying Foster, Yolanda was diagnosed with Lyme disease, and in late 2014, she suffered a relapse, which left her unable to read, write and even watch television. At the time, Foster spoke of her health crisis in her Bravo blog, and on social media, she continued to document her hardships.

Because of Yolanda’s openness about her illness, as well as the ups and downs of it, there has been quite a lot of speculation into whether or not Lyme disease is her true diagnosis.

On the popular Bravo reality show, Taylor Armstrong, a former full-time star of the show, made a guest appearance, and during her visit with the ladies, she admitted to having questions about Yolanda’s health due to her inconsistent social media feed of “happy selfies, sick selfies.”
