NeNe Leakes wants the world to know that she is in no way your “average day” grandma. She’s a “sassy, fashion-forward grandma!”

The star of “The Real Housewives of Atlanta” is showing off her new granddaughter Bri’Asia Bryant in the latest issue of In Touch Weekly, where she reveals that she was shocked when she found out that her 22-year-old son Bryson (the one who’s always in trouble or jail) had gotten his 21-year-old girlfriend Ashley Hill pregnant.

In fact, NeNe says she didn’t even know until Bryson’s girlfriend was more than six months pregnant!

“I only found out about everything because I ran into Ashley when she was more than six months along,” the Real Housewives of Atlanta star tells In Touch in an exclusive interview. “I said, ‘You look pregnant.’ And she said, ‘Hasn’t Bryson told you?’ But he hadn’t because he knew that I wouldn’t approve of him having a child so young.”

“I didn’t feel like he was ready for such a big responsibility,” she says. “I was his age when I had him, so I know how tough it is. I didn’t want him to make the same mistakes that I did. I needed to let it sink in.”

However, once little Bri’asia Bryant was born in mid-June, no-nonsense NeNe melted. “I always wanted to have a girl,” she says, “and now I have one! She’s just adorable.”

Not only has NeNe done everything she can to make sure that her son’s girlfriend won’t have to struggle financially — “I paid for everything in the nursery: the clothing, the diapers. I don’t want her to feel strapped,” she says — she’s gone completely “crazy” buying gifts for the baby, including “little dresses, sparkly headbands, and Gucci shoes … We just love her,” NeNe gushes to In Touch.

And while at first she was reserved about being called “Grandma,” the 44-year-old outspoken star now embraces the name! “Forty is the new 30. I’m a sassy, fashion-forward grandma!”
