Keshia Knight Pulliam Announces First Pregnancy

— -- It’s hard to believe the actress who played the beloved little girl Rudy Huxtable will soon be the mother of a little girl herself.

The former co-star of "The Cosby Show," actress Keshia Knight Pulliam, announced Monday that she and husband Ed Hartwell are expecting a baby girl.

The actress, 37, posted to her Instagram to share the good news. In the selfie, Pulliam is holding a pink-frosted cupcake with a small baby decoration on top.

“Surprise!!! We have a new addition coming soon...tune into #KandidlyKeshia this week for the details!!” the caption reads.

A friend of Pulliam’s also posted a photo to Instagram to celebrate her friend’s pregnancy, which is the first for the couple, though Hartwell has a son from a previous relationship.

“Our Sunday Family Dinner turned into a BABY REVEAL!!! #ItsAGirl!!! Congrats to @keshiaknightpulliam and @edhartwell!!! #TheHartwells!!” her friend wrote.

Pulliam and Hartwell wed in January after a brief engagement.
