NeNe Leakes’ husband Gregg Leakes died from colon cancer on Wednesday at age 66 – and while he appeared regularly on the often contentious "Real Housewives of Atlanta," many among the reality circle revered the real estate investor as a beacon of objectivity.

"I am heartbroken over the passing of Gregg Leakes, a wonderful man," Bravo TV executive producer, Andy Cohen wrote on Twitter following the news. "I jokingly called him 'Pastor Leakes' but in truth he was a strong voice of reason & commanded great respect among the entire #RHOA team. I am sending love and strength to @neneleakes & the entire Leakes family." 

Gregg had actually married NeNe Leakes twice during his lifetime – first in 1997, and again in 2013 after a 2011 divorce. He began appearing on "Real Housewives of Atlanta" alongside his wife in 2008, continuing to appear through 2019. In 2013, their second wedding was featured in the spinoff show, "I Dream of NeNe: The Wedding."

His harrowing bout with cancer was chronicled on the show as he underwent surgery in 2018 to remove part of his colon.

Many of NeNe’s former "RHOA" costars also took to social media to honor Gregg and speak to the man he was, including her frequent frenemy Kim Zolciak Biermann, whose feud with NeNe played out both in reality TV and in the public sphere.

"Always the voice of reason," she wrote over one picture shared to her Instagram Story. "Sending you all my love to @neneleakes and your family." Zolciak Biermann also shared another photo of Gregg alongside her husband, Kroy Biermann.
