(Yahoo!) - Ever wonder why Kim Zolciak is so obsessed with timeliness? Perhaps it's because she's busy non-stop procreating

The former Real Housewife and current star of Bravo's "Don't Be Tardy … " is expecting her fifth child, InTouch magazine confirms. It will be her third child with NFL player hubby Kroy Biermann.

"Kim and Kroy are so excited to be pregnant again,” a source told the mag, “she’s been trying to keep it quiet -- she didn’t realize she’s showing as much as she is.”

Zolciak was spotted rocking a baby bump on a Florida beach over Memorial Day weekend. She was also seen puffing away on cigarettes, not the first time the reality star has indulged in the universally panned habit for pregnant women.

Kim and her pigskin-handling man have two young sons: Kroy Jagger, born in May 2011, and Kash Kade, born just nine months ago, in August 2012. She also has two girls, Brielle and Ariana, from a previous relationship.

"I would like to try for a little girl," she told InTouch in December of expanding her family with Biermann.

The more ladies the merrier … someone has to inherit all those wigs.
