Sneak Peek: Kim Zolciak Has a Freakout and Bad Pre-Wedding Breath

The day is officially here, where fans get to watch Kim Zolciak take her big walk down the aisle into the arms of her boo, Kroy Biermann on Don't Be Tardy for the Wedding. We've seen the episode and can tell you it is so, so good, and there's even a little sneak peek for you in the meantime.

People.com has an exclusive clip of the big hour-long special (starting at 9p), showing Kim feeling the pressure big time as the clock ticks down towards wedding time. She's hot, she's stressed -- and apparently, she's got some pretty foul breath (at least in her mind) and has to brush her teeth, veil and all. It's hard to say for sure, but there's a good chance this will be the first time you'll ever see a bride in full veil spitting out toothpaste while helicopters buzz over her house.

Watch the clip at People.com, and be sure to tune in to the big Tardy wedding episode tonight at 9pm.
