She disclosed this joyous news on her Instagram handle as she posted a sweet snap of her son Titan Jewel, six, looking over the newborn baby.
The 39-year-old music star welcomed the little boy on 21st January and revealed she and her husband , Tim, 46-year-old, have decided to name him Noah Jon Weatherspoon.
In the caption, she wrote: “On the 21st day, of the 21st year, of the 21st Century, Noah Jon Weatherspoon Greeted us! We are truly grateful,” followed by four red heart emojis.
She went on to add the date and time of birth alongside the weight of the child as she wrote: “1.21.21, 8:13pm, 7lbs. 8oz 19in”.
Fans were quick to congratulate the singer, as one person commented: “congrats! Blessings to you and your family!” followed by two heart eyes emojis.
“Ahh Congratulations @kellyrowland wonderful news,” a second chimed with six kissing emojis.
While a third added: “Blessings to you and your family and congratulations on your new bundle of joy!” with a pink heart emoji and a rainbow emoji.
Kelly announced she was pregnant with her second child back in October on the cover of Women’s Health magazine.
She said in the interview with the publication: “You still want to remind people that life is important.
“And being able to have a child…I’m knocking at 40’s door in February. Taking care of myself means a lot to me.”
Kelly talked about expecting pregnancy, and said : “We had been talking about [having another baby] loosely, and then COVID happened, and we were just like, ‘Let’s see what happens’
“I was thinking, Oh my god, my fans are gonna be so disappointed.…They wanted an album first, but they got a baby! And I was like, ‘I have to figure this out so they get both.'”
Then, she opened up on her preparation for the child, and adding: “I am obsessed with sandwiches. A turkey sandwich with mustard and rye and sprouts and onion and sometimes a little avocado.
“I don’t really count calories. Trust me, there are some days when it’s hard to look at seeds and nuts and fruit when everybody’s got french fries and burgers and Roscoe’s chicken and waffles at midnight.”
