The celebration of life was held at NeNe's Linnethia Lounge in Atlanta, Georgia, on Monday, where a number of former Real Housewives of Atlanta castmates came together to pay their respects and celebrate Gregg's life.
Among those spotted at the event were past and present RHOA stars including Lisa Wu, Phaedra Parks, Marlo Hampton, Porsha Williams and Eva Marcille.

Ahead of Monday's gathering, NeNe took to Instagram and shared a throwback photo of herself and Gregg sharing a sweet kiss.
"Today we celebrate you Gregg with love, just the way you wanted it💔" she captioned the post.
Gregg and NeNe's son, Brentt, shared a photo from the celebration of life event to his Instagram story, to commemorate his father.
