After much speculation multiple sources are confirming that reality star Kim Zolciak is pregnant with her fifth child just nine months after giving birth to her second son with husband, Atlanta Falcons player Kroy Biermann.

"Kim and Kroy are so excited to be pregnant again," a close friend of the couple revealed to In Touch Magazine, on newsstands now.

On May 27th, the "Don't Be Tardy..." star was spotted on the beach debuting her baby bump during Memorial Day vacation.

Sources revealed to the magazine that "She's been trying to keep it quiet - she didn't realize she's showing as much as she is."

Zolciak already has two daughters, Brielle, 16, and Ariana, 11, from a previous relationship, and added sons Kash and Kroy Jr. to the brood following her relationship with Biermann.

The reality star has not been shy about expressing her desire to expand her family particularly with the addition of a baby girl.

Back in December Kim told In Touch, "I would like to try for a little girl."

However the source told the magazine that this pregnancy was a surprise to the couple, "They didn't plan it, but they're thrilled."

Now that her pregnancy is confirmed we are curious to see whether Kim Zolciak will explain the photos of her smoking on the beach.
