Kim Kardashian: Sweating Makes Me Feel Sexy

Kim Kardashian is one of Hollywood's sexiest stars, but ask the sultry reality gal what she thinks is sexy and you might be surprised — it's working up a sweat.

"I definitely think that just being confident is being sexy so personally when I'm in shape I feel the sexiest," Kardashian added. "It's always about me getting in the gym and staying with it and staying motivated. It's also from within; you should feel sexy when you wake up in the morning. You've just got to stick to your workout regime; so many people start and then stop."

The queen of curves does look pretty perfect these days, but she says there is still room for improvement.

"I need to start eating better," Kardashian added. "That's going to be my new thing."

And even though that was quite a few weeks ago, we caught up with the 28-year-old again last week and while she admitted she still hasn't nailed the nutrition thing, she's launched her own workout DVDs and is encouraging gals to send her their pics as part of her "Fit in Your Jeans" initiative.

"I don't go on the scale but in my closet I have a whole heap of jeans. I have on one side a whole heap of the skinny ones that I don't fit into, they're the ones I could lose a few pounds to get into and I only really had two pairs I would wear over and over all the time," she told Tarts at the launch event at Kitson Boutique on Robertson Boulevard in West Hollywood. "I now fit into the ones on the other side of the closet I can fit into a little bit better. The ones I'm wearing today I couldn't fit into at all six months ago."

So all that squatting, sweating and striding is certainly paying off when it comes to Kimmy's fabulous figure — and even though she has no problem pointing out that she does suffer from a few female flaws like (gasp!) cellulite, the reality starlet hasn't always felt good in her skin.

"I go to so many parties and red carpet events and you always want to look your best, but I always felt I was never 100 percent confident and comfortable and there's no reason you should feel that way," Kardashian added. "I wanted to do something that would change my life and this DVD has taught me so much and I've changed my lifestyle to incorporate working out every day. I love it and I feel good, the whole goal was too feel good."

But which body part does she have a love/hate relationship with?

"My butt," she laughed. "I've really had to tone up, this has taught me so many tricks. I partnered with a trainer, Jennifer Galardi, I'm not an expert so I wanted to learn. I need help like everyone else. It's been a great challenge for me. (NFL beau Reggie Bush) was there thru the whole process too. We incorporate little things in our workout to do together."

But let's hope Reggie Bush has good manners because there's one thing in-particular that will totally Kim off ...

"The unsexiest thing a guy can do? Probably fart," she told Tarts recently at TV Guide's "Sexiest Stars" soiree, adding that that is the worst thing a woman can do in an intimate situation too.

Holly Madison Stripping For $$$

Last month Holly Madison assured Pop Tarts that she was totally done with taking off her clothes.

"I'm never getting naked again," she vowed. "I'm over it, I've done it so many times. It is time to switch it up."

But a little money can obviously go a long way and thanks to a lucrative Sin City offer it seems the former Playboy pin-up and DWTS contestant has had a sudden change of heart. Madison is getting ready to strap on her dancing stilettos once again to take over the role of "Bo Peep," a modern woman who has yet to find her own confidence and sexuality, currently played by "General Hospital's," Kelly Monaco in the hit burlesque PEEP SHOW at the Planet Hollywood Resort & Casino.

However unlike Monaco and her co-star Mel B, we are told that Miss Madison will be going topless despite that recent no-nudity clause and is set to make her stage debut on June 22. But that isn't the only Vegas project the blonde bombshell has burning.

"I'm producing and starring in my own reality show," she recently told Tarts. "It will be about me and my friends here in Vegas over summer. That's all I can say right now."
