Khloé Kardashian To Be Bikini-Ready By June

Khloé Kardashian recently admitted that for her, weight is a "lifetime struggle." But the E! reality star won't end her body battle without a fierce fight.

"I'm in a working-out process, and I'm definitely back on trying to lose weight," Kardashian, 26, told PEOPLE Friday while promoting her Kardashian Glam Shapes SillyBandz at Kitson in L.A. "It's about being healthy, though. I believe in working out, eating well … I do everything in moderation. I don't like people who do extreme, crazy diets."

The youngest Kardashian sister wants to be a role model to others with similar struggles.

"I don't know if people think celebrities don't have insecurities, but … everyone does," she says. "Mine personally is weight. I could be as skinny as ever, but to somebody else, I may not ever be good enough. My weight fluctuates, and I accept that, and it's my life struggle, but I just wanted to point out that I'm normal, and everybody has their own things."

Fueling her is a desire to feel sexy again in a bikini. "That's my mission," she says. "I'm going to Mexico in June."

Kardashian also joked that by then she might even be ready to wear a two-piece on the cover of PEOPLE.

Holly Madison Told To Lose Weight For Show

Producers ordered former sexy Girl Next Door Holly Madison to slim down for her role in burlesque Las Vegas show Peepshow, she told Radar Online in an exclusive new video interview.

Madison was "shocked" when she was told she's too fat, and needed to drop some pounds for the hit stage production.

"I always thought I looked fine. It was a shock to me when they told me to lose weight," the former Playboy Playmate, 32, told Radar Online.

"I'm still up in the air over what to do. I feel like I changed my eating habits to really healthy; I've lost a few pounds.

"I'm still getting there and deciding if I even want to lose weight.'

Madison, the 5'7" blonde who was one of Hugh Hefner's three girlfriends, said she was comfortable with her weight.

"I just feel like I market myself as a sex symbol, I don't market myself as a fitness model or a professional dancer so I feel like the way I look is fine!" she said.

"I don't think I need to lose weight!"

Tune in to the season two premiere of her hit show Holly's World Sunday, which premieres on January 23 at 10:30 pm on E!.

Kendra Wilkinson: How I Lost 40 Pounds

Just how did Kendra Wilkinson lose her baby weight?

With a lot of hard work and trips to the gym "no matter what," she told Us Magazine at the shoot for Us Weekly's Top Transformations.

As the star of E!'s Kendra, Wilkinson says she usually logs 30 minutes to an hour in the gym for four days of the week. If it's in the morning, she'll have a harder, longer workout. If it's at night, she explains, she'll just do simple stretches and a good run.

"When I work out I just go based off of how I feel," the 25-year-old mother told Us. "It depends on how I'm feeling and what I did the night before."

Although she used to give into temptation, Wilkinson has found a way to fight them. "I take a little bite instead of the whole thing."

With 40 pounds lost, the hard work is paying off. "I feel like I'm on my way after a good workout to a body I love," she told Us.

Kim Kardashian's Quickest Slim-Down Ever

After spending two months in New York City to film Kourtney and Kim take Manhattan, Kim returned to Los Angeles 10 pounds heavier. With her hectic schedule, not only did Kim indulge but without a trainer to push her, she also skipped regular workouts. She and Kourtney would "eat nuts and hot dogs from street vendors every day," Kim tells Life & Style. "It was crazy. We had no time to stop and eat well or even look for healthy food. We just had to grab what we could as we ran past the food carts."

Since then, she's been on a mission and in just two weeks, the 5-foot-2 bombshell is back to a size 2! She's committed to daily workouts with either her long-time trainer, Gunnar Peterson, or what she calls her early-morning "rise and grinds" at Barry's Bootcamp. "I'm doing vigorous workouts all the time," Kim told Life & Style at the Borders in Century City, Calif., between signing copies of Kardashian Konfidential. "I work out with Gunnar -- mostly weights. Then I do boot camp. I alternate every day. One day trainer, one day boot camp."

Kim also been eating portion controlled meals from Sunfare, a gourmet-meal delivery service that Britney Spears, Eva Longoria and other celebs also rely on. "It's the only diet I can stick to," Kim tells Life & Style. "It makes me eat healthy because the food [breakfast, lunch, dinner, snacks] is at my house when I wake up."
