For those who grew up watching Keshia Knight Pulliam on "The Cosby Show," she'll always be that little girl with a big personality. But she's all grown up now — and she has a little girl of her own to prove it.

The actress revealed the happy news via Instagram Monday with a photo of her holding a pair of tiny feet in her hand.

"Ella Grace has arrived!!!" she wrote.

In an interview with ET at the time, Pulliam alleged that Hartwell had been unfaithful to her, and added, "The part that hurt me the most when he filed for divorce was that he had asked me to give him another chance, and I was willing to do that and forgive him, for our family."

He posted a smiling photo of himself to Instagram — with the new mom and his new niece in a hospital bed behind him — along with a message to Ella: "We've been waiting for you!!"
