The fun family attended Keep a Child Alive's 10th Annual Black Ball in New York City on Thursday, Nov. 7, and E! News caught up with the 28-year-old R&B star.
"He is amazing," the singer, who looked stunning in a revealing red gown, said about her little boy. "He swims by himself, he is so independent, he is extremely smart. I ask him to count to tens from 500 to 100 and he can do it. His rhythm is kind of impressive!"
Egypt was matching his gorgeous mom, looking casual chic in a red and white jacket and sneakers.
So does her son want a sibling and will the couple add baby No.2 to the mix?
"I bet he does," Keys said with a laugh. "Not right now, but never say never!"
And he most certainly does. When asked if he wants a brother or a sister, the cute munchkin enthusiastically replied "Yes!" with a high five.
Keys also couldn't help but gush about her hubby, and revealed he is the "most romantic person in the world."
"He is very innate and he is very thoughtful and he always introduces me to new things, which makes us just really compatible with each other," she explained. "He is always showing me new and incredible artists or a new beautiful place to go, another way to think about how to approach something. It's so incredible to have someone that you can rely on and help you grow in the most supportive way so we are a really good couple."
