"Todd and I have been waiting so long for his delivery and he is so very perfect," Burruss told People, adding that their "bouncing baby boy" arrived at 8:42AM, weighing seven pounds and six ounces.
Tucker had posted a photo on Instagram from inside the hospital the morning of January 6 with the following caption: "Getting ready for Baby Tucker 1.6.16! I can't wait to meet my little man!"

"We're so thrilled to announce the news of our bundle of joy, it's a dream come true," Burruss, who has her own record label, told E! News.
Tucker also told the website Kaela and Riley "couldn't be happier about becoming big sisters."
Burruss, who also starred on The Kandi Factory, underwent in-vitro last year to get pregnant again. Fans saw a cute glimpse of her growing baby bump when she posted an image on Instagram New Year's Eve featuring Tucker and some of her girlfriends.
Burruss, 39, and Tucker got married in April 2014 and announced the reality TV star's pregnancy in July 2015. They reportedly met when Tucker was a line producer on The Real Housewives of Atlanta.
