Nicknamed "The Tush" by celebrity bloggers, the socialite and one-time Paris Hilton
party pal is set to star in the reality series Keeping Up with the Kardashians
, premiering Oct. 14 on E! Kardashian, 26, who owns the L.A. fashion boutique Dash with her two sisters, spills her secrets to PEOPLE's Jennifer Garcia.
IS IT REAL OR PADDED?
It's all real. I do not have butt implants. Everyone in my family has these big fat butts. It definitely came from my Armenian side, and I'm proud of my heritage. I do like my shape.
HAVE YOU ALWAYS LOVED IT?
When I was 11, I hated it. I would cry and pray that it would stop growing. But in high school I started to like it. Now I embrace my big butt.
WHAT'S THE BEST WAY TO SHOW IT OFF?
In tight-fitting dresses. It has to be tight in the waist and tight right under the butt. Hervé Léger and Mark Wong Nark are pretty much the only labels that fit. Oh, and Dolce & Gabbana too. Everything else I have to get tailored. I'll have the waist taken in and my butt literally cupped. My tailor thinks I'm completely nuts because I bring in these tight dresses and even formfitting pencil skirts and tell him to take them in more.
HOW IN THE WORLD DO YOU BEND OVER IN THOSE OUTFITS?
You don't bend over. You bend your knees and go straight down and come right back up. Ladylike. And when I wear those tight Hervé Léger dresses, sometimes I can't wear underwear, so I definitely know how to exit my car without having any inappropriate paparazzi shots.
WITH THAT WARDROBE, YOU MUST WORK OUT AND DIET LIKE CRAZY!
I'm doing something called Free-Flow. It's like martial arts on treadmills. It's so insane and works every muscle. I go for two hours, three times a week. And I just started the Zone food delivery, but I cheat.
EVER WORRY ABOUT LOSING YOUR PERKY POSTERIOR?
I have this towel trick. When I get out of the shower, I drape the towel at my waist. It just sits on my butt and stays there the whole time while I do my makeup or use it to wipe off stuff. But when I lose weight, it falls off, so then I know I have to start eating.
