"We've grown apart but my love & respect for @officialdfoster is still the same," the 51-year-old wrote. "He's been very good 2 me so pls don't judge our journey!"

A source close to Yolanda told ET on Wednesday that the couple ultimately decided to divorce after four years of marriage because "David is a very busy man, and always put work No. 1."

"Sadly we have decided to go our separate ways," the couple told ET in a joint statement. "We've shared nine beautiful and joyous years together. During that time we experienced love, friendship and the inevitable challenges that come with managing a marriage, careers, blended families and health issues."

"We are grateful for the years we've spent together and believe wholeheartedly that we did our best,” the statement continued. "We hope that we can pave the road ahead of us with all we've learned and with the love and respect we will always have for one another."

Yolanda, who is battling Lyme disease, penned a lengthy post on her Bravo TV blog on the same day as the divorce announcement, writing, "Becoming chronically ill has definitely given me a greater understanding of human nature, and I've learned to accept people's lack of long-term compassion for others while they live their busy lives."

"I am blessed to have a voice and a platform that can bring awareness to not only my disease but to the most profound lesson of it all, which is to lead a life with compassion, kindness, and without judgement, for everyone you meet is fighting a battle you know nothing about," she added.

In happier news, Yolanda is celebrating the success of her two model daughters, 20-year-old Gigi Hadid and 19-year-old Bella Hadid, with her previous husband, Mohamed Hadid. The two are also parents to 16-year-old Anwar Hadid. David, 66, has been married four times and has five daughters.

Yolanda took to social media to share her excitement about Bella's Chanel runway debut.
