Kim Zolciak Needs a Toothbrush (and a Chill Pill) Pre-Wedding: Video

Kim Zolciak's wedding day dramatic? No way!
On Thursday's Don't Be Tardy for the Wedding finale, the Real Housewives of Atlanta star will finally walk down the aisle – but not before battling a case of pre-wedding jitters. (Watch a clip above.)
"People kept asking me, 'Why are you not nervous?' " says Kim. "And then it just hit me. And so here I sit: a nervous wreck."
Kim's daughter doesn't help things when she rushes into the room buzzing about media helicopters "swarming" the house, though Zolciak's team of assistants tries to keep her calm.
Still, she can't help but fixate on a more substantial (and stinky) problem: her "ungodly" breath.
Luckily for hubby-to-be Kroy Biermann, there's a toothbrush nearby!
The special hour-long finale episode airs Thursday (9 p.m. ET) on Bravo.
