That's a major no-no, Kim! Just two days after finally confirming her fifth pregnancy on her Real Housewives of Atlanta spinoff series Don't Be Tardy, Kim Zolciak was spotted lighting up a cigarette in an Atlanta parking lot on Thursday, June 27.

The reality star, who showed off a very noticeable baby bump in a form-fitting black tank top and grey sweat pants, attempted to hide the cancer stick behind a cup, but not before the expectant mother was snapped puffing away.

Smoking while pregnant can lead to health complications for both the mother and the child, including a premature birth, infants with low birth rates, miscarriages, and in some cases, even long-term lung damage to the baby.

Us Weekly first reported that Zolciak and husband Kroy Biermann, 27, were expecting a bundle of joy three weeks ago. On the show, the couple beamed as Zolciak read the results of several at-home pregnancy tests aloud.

"Pregnant, pregnant, pregnant, pregnant, pregnant, pregnant," she said excitedly. "Kroy, we have not one negative test. How exciting is that, love muffin? You did it again lovey … Are you excited, love muffin? It must be the athlete sperm." 

Zolciak, 34, is already mother to four children -- sons KJ, 2, and Kash, 9 months, with Biermann, and two daughters Brielle and Ariana, from previous relationships. Zolciak and Biermann tied the knot in 2011.
