The 'Good Morning America' presenter couldn't hide his delight as he beamed broadly throughout 'Fox NFL Sunday' and explained his daughter Tanita, 32, had given birth to a baby boy.

The former New York Giants player said: "Yes, I am a grandfather everybody.

"My daughter Tanita had my grandson, Onyx, is his name.

"That means black, in case you were wondering.

"It's really special because I know you guys have gone through this.

"I'm just happy to be able to join you in that club."

After telling him "congrats grandpa", fellow panellist Howie Long said: "Grandkids are great."

Terry Bradshaw then asked how Tanita was doing after giving birth and Michael, 52, replied: "Daughter is fantastic.."

Tanita - who is the father-of-four's eldest child from his first marriage to Wanda Hutchin - hadn't publicly mentioned her pregnancy, with the illustrator not having posted on Instagram since last October.

Michael - who also has Michael Jr., 29, with Wanda, and 19-year-old twins Isabella and Sophia with second wife Jean Muggli - previously admitted Tanita is very like him.

He previously told New York Family: "[Tanita is] kind of like me in the sense that she has a very strong personality, but a silent strong personality.

"She’s not going to be one to walk into a room and make it all about her. She definitely has an opinion and she's very smart and she knows what she wants, which I love about her."

The baby is further good news for the family as Isabella was declared cancer free in July after being diagnosed with brain cancer last October.

The teenager revealed the news in a YouTube video titled ‘Goodbye Hospital’, grinning as beamed as she told her followers she had received a “great, great scan” from medics following her final chemotherapy treatment.

Isabella added: “Everything was clear. Cancer-free and everything is great. I don’t have another doctor’s appointment until October.

“I miss my doctors already and everyone who’s helped me because they’re all so nice.

“I feel like I’m just saddened today knowing that I wasn’t gonna be going back for a while because I love them so much. So, that was my last hospital vlog until October!”
