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.

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.

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."
