Gregg was diagnosed with Stage III colon cancer in 2018, and though the illness went into remission for two years, Nene shared in June that the cancer had returned.

Over the weekend, the RHOA star gave updates on her husband's condition and said he was "transitioning to the other side." The couple wed in 1997 and share a son, Brentt (22).

On Monday, Nene posted an image of the word "Broken" on her Instagram. On Thursday, she shared a video of herself dancing with Gregg, captioned with broken heart emojis.

Following the news, the 53-year-old's cast mates and several celebs paid tribute to her late husband.

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

Porsha Williams shared a picture of Gregg and NeNe on her IG with the caption, "Truly heartbreaking news, Love and prayers for dear NeNe & the Leakes family."
