ET recently spoke with Eva Marcille, who appeared alongside NeNe on RHOA for three seasons. When asked about Gregg's battle with cancer, the mom and model said there aren't "any words" to properly say to send her love to NeNe and the Leakes family.
"Gregg was... Is a real one. Gregg is an amazing, amazing man. And he has been fortunate to be coupled with an amazing woman. And I don't think there are any words to properly say to send my love. I did text NeNe and just sent my love, because I don't know what there is to say. It's one of those things where it's life, but it doesn't make it any easier. So I just pray for their family," Marcille told ET.
She continued, "Gregg's an amazing dad. He has...The man made some boys. So I pray for his family, his kids and for NeNe at this time, that they get some sense of peace in the middle of all of this. Gregg, I don't have a bad memory of him, or a foul word, ever. He has always been an amazing guy. And I know NeNe as well as I do because of Gregg, actually, because we have something in common we won't talk about. But that's my buddy. Gregg is a great guy and I just send love and well-wishes, and I just told NeNe God's working on her behalf."
Gregg and NeNe married in 1997, but she filed for divorce from him in 2010. However, the couple reunited and remarried in 2013. He is survived by his six children -- Daryl, Damian, Dexter, Denton, Katrina as well as his and NeNe's son, Brentt. He was also a stepdad to NeNe's son, Bryson, whom she had from a previous relationship.
