Fearing wedding crashers, Kim and Kroy amp up security measures to mythic proportions, enlisting armed guards and attack dogs. Kroy surprises Kim, who gets sick the day before the wedding, with some major bling for the wedding. Derek J and Niki try their best to convince Kim to wear her real hair on her wedding day. Kim isn't keen on the idea but agrees to at least show them what she's been hiding under that wig!

It's the morning of the big day, 11/11/11, and while Kroy's at practice, Kim has to make sure everything is perfect before she walks down the aisle. Kim and her best friend, Jen, reunite and Kim's assistant Niki steps into the role of Matron of Honor. With just a couple hours to go, Colin Cowie's crew is still putting together Kim's wedding and Derek J still hasn't cut Kim's wedding wig.

Nerves continue to fray as guests arrive, including paparazzi in helicopters. Kim is swept up in the emotion of being a bride, but her special day turns cloudy when her mom starts making demands. After a dramatic confrontation, Kim still manages to make it the happiest day of her life, the start of her forever with Kroy.
