Kardashians in Exclusive 'Nightline' Interview

May 24, 2010 — -- Kim Kardashian has never had work done on her nose, Khloe Kardashian's wedding was not paid for by E! and, no, the Kardashian clan does not intend to pull the plug on the reality TV show based on their lives.

Those are just a few of the myths the family is out to dispel.

"We do the show 'cause we're happy and it's fun for us," said Khloe Kardashian. "So until it starts becoming a pain or something that we don't want to do..."

"Season 52," joked mom, Kris Kardashian, referring to her youngest daughter: "Kylie gets married."

In an exclusive interview, the women at the core of "Keeping Up With the Kardashians" -- Kris, Kourtney, Kim and Khloe -- sat down with "Nightline" co-anchor Cynthia McFadden for a conversation that ranged from their business empire to who has had plastic surgery and who takes the longest to get ready to Kourtney's baby and Kim's Playboy appearance.

"We have a really good time doing what we're doing," said Kim. "We love every project that we're into. We're just having a good time."

Kourtney Kardashian, who gave birth to her first child, Mason, a son, in December 2009, said her breast implants were no secret.

"I have had breast implants, but it's so funny 'cause it's not a secret, I could care less," said Kourtney. "It's so funny because the 'before' picture that they [In Touch magazine] showed was after I had my boob job, so I'm like, they should have written 'before Mason' and 'after Mason.' Like my boobs have like tripled since breastfeeding."

"Oh, right," said Kris, with a wry smile.

Kim denied rumors that she had plastic surgery on her breasts or nose.

"Trust me honey," she joked to McFadden, "if I take this bra off you will tell me I need to get them done. I'm totally not against plastic surgery. ... I've tried Botox before. That's the only thing that I've done."

McFadden asked Kim about her nose.

"I've never had my nose done," said Kim.

"None of us have had our nose done," said Kris.

"But what's funny," said Kim, "is about my nose, it's my biggest insecurity. I always want to get my nose done. ... I went to a doctor, I had them take the pictures, he showed me what it would look like and it just didn't-- It-- I wouldn't look the same."
