Kim Zolciak's 2013 pregnancy is a thing of rumor no more! The Don't Be Tardy star has confirmed that, not only are her and husband Kroy Biermann soon going to be the parents of five, but he has officially adopted her two daughters from a previous relationship!

The news was made public during the June 25 episode of their reality show, as cameras captured the 35 year old reading the results of several pregnancy tests taken all at once, saying: "Pregnant, pregnant, pregnant, pregnant, pregnant, pregnant... Kroy, we have not one negative test."

"How exciting is that, love muffin?" Kim Zolciak went on to say to her Atlanta Falcons footballer husband. "You did it again, lovey... Are you excited, love muffin? It must be the athlete sperm."

The happily married pair, seen here in March leaving the 2013 Bravo Upfronts party in New York City, have already welcomed 2-year-old son KJ and 9-month-old son Kash since marrying in May of 2010.

This time, it's no secret the former The Real Housewives of Atlanta star is hoping for a girl.

"I personally would love a little girl, because Brielle's going to be 18 soon, [and] Ariana's six years away from being 18," she went on to say to Biermann during the episode. "If this next baby is a boy, she'd be alone in the house with three sons and her husband once the girls went off to college... That's a life of four-wheelers and football."

"This is it," she added, explaining her fifth pregnancy is to be her last. "You better hope you get a little girl, because this is it!"
