Kim Zolciak may have smoked like a chimney back during her Real Housewives of Atlanta days, but now that she's preggo with her fifth child, her cigarette habits are no laughing matter. Recent pictures that surfaced of Kim puffing on cigs have the mama fuming.

The Don't Be Tardy star went on Twitter to fire back a response to her haters.

"There are ALOT of things I let slide HOWEVER misleading accusations and claims I will NOT tolerate! My legal team will handle from here," Kim announced.

We'd like to think that Kim wouldn't put her fifth kiddo at risk, but it's hard to deny that a visibly pregnant Kim isn't smoking in these pictures.
