Season six of Real Housewives of Beverly Hills will be Yolanda Hadid's last.

The 52-year-old reality star announced that she's leaving the hit Bravo show with an Instagram post on Wednesday.

"I would have loved a more graceful exit then 'Season 6' but sometimes we don't get to control the ending of the chapters in our life... I am leaving what's over without denying its past importance in my life," Hadid wrote. "I believe that every exit is an new entry and with that in mind I say goodbye to my @Bravotv Family as I continue to focus on a my recovery, my children and bring back the privacy within our home."

Hadid thanked her fans for their support.

“Thank you to all the fans for your love and unwavering support these past 4 years," she concluded. "I am grateful for the housewife experience and all it has thought me. I am excited about this choice and look forward to the next chapter of my life... #RHOBH #TimeToSayGoodbye with #Gratitude."

executive producer Andy Cohen reacted to the news on Wednesday, tweeting, "We love you @YolandaHFoster #RHOBH."

Hadid joined RHOBH in season three in 2012. She has been open about her struggle with Lyme disease on the show, and last season, she found herself being questioned about her diagnosis by her fellow housewives. Hadid also said that two of her children also have Lyme disease -- 19-year-old Bella and 16-year-old Anwar -- although her eldest child, 21-year-old Gigi, has not been afflicted.

In January, Lisa Vanderpump admitted she regretted questioning whether Hadid's children had Lyme disease.

"Over the years of interacting with all of the children there had never been any mention of illness," Vanderpump explained in a blog post. "[Their father] Mohamed had always said they were fine, but that is their prerogative as parents, whatever medical issues or information they choose to divulge. I obviously interpreted that as they were not infected by this insidious disease, and as it is not contagious, I understood them to be healthy."

"I had no reason to question their well-being," she added. "I love and adore all three of them, for sure."

Last December, her ex, musician David Foster, came to her defense.

"I have always had and continue to have the utmost respect and love for Yolanda, which is why it is so frustrating to see headlines questioning her chronic debilitating illness," Foster said in a statement obtained by ET. "I have been by Yolanda's side over the past four years to the best of my ability as she battled with the complexities of her Lyme diagnosis. I am incredibly proud of Yolanda's determination and mission to find a cure, and how brave and open she has been by sharing her story in the hopes of changing the future for others."
