Khloe Kardashian: I'm "Massive" Next To Sisters

It's not easy being the "biggest" Kardashian sister.

In the new issue of Us Weekly, out Wednesday, Khloe Kardashian admits red carpet events with older sibs Kim and Kourtney can take their toll on her self esteem.

"They are 5-foot and 5-foot-2, so I look massive next to them," Khloe, who is 5-foot-10, tells Us. "Everyone expects me to be 9 feet tall and weigh 200 pounds [when they meet me]."

26-year-old Khloe -- whose mom Kris Jenner even criticized her weight in a recent episode of Khloe and Lamar - has "struggled with her weight since she was 8 years old," a family friend tells Us. "She was always taller and developed much broader shoulders than her petite sisters."

And the E! reality star, happily married to basketball star Lamar Odom for over a year, says she first gained weight following Kris' divorce from her late father, famed OJ Simpson trial attorney Robert Kardashian Sr.

"My brother [Rob] and I were always heavy. They gave us food to keep us comforted. All we did was eat crap," she recalls.

Classmates and even her mom's friends noticed that Khloe's older sisters Kim, 30, and Kourtney, 32, stayed skinny despite the family turmoil. "I had older women tell me, 'You should really work out,'" she explains. "It really got to me."

Her initial response? A teenaged Khloe hit the gym, working out three times a day and eating tiny meals. She went from a size 12 to 0.

"I started to get a positive response from people when I was losing weight," she admits.

Kris Jenner Slams Khloe for Gaining Weight

On Sunday's Khloe & Lamar, Khloe Kardashian, 26, comes under fire from her mom, Kris Jenner, after she packs on a few extra pounds.

As Jenner sees it, her daughter's weight gain makes her a less than ideal spokeswoman for the Kardashians' Quicktrim diet supplement. Jenner also accuses Kardashian of sabotaging the brand.

"You don't care and it's very very upsetting to me because I've worked so hard at creating what I think is a great deal for you girls and you're not pulling your end of the weight," Jenner says in a sneak preview of Sunday's all-new episode. "I feel like you could not chat about how many cookies you're eating in between meals [to the media]..."

Kardashian, on the other hand, feels torn as she struggles to maintain a healthy weight in an effort to conceive her first child with husband Lamar Odom.

"To tell me I'm ruining a whole brand because of my weight gain makes me feel like s--t. Get over yourself. You're such a f--king raging lunatic and you're so evil," she snipes to Jenner. "I'm too f--king fat, too f--king that. Do you want me to get pregnant? Do you want me to lose weight? You tell me you want me to have a baby every second, but I can't be on some crazy diet. I just don't get what you want out of me!"

Khloe: Lamar Wanted to Quit Show "3 Days In"

Two days after the premiere of Khloe Kardashian and Lamar Odom's new reality series, Khloe & Lamar, the L.A. Lakers star is already struggling to adapt to the rigors of fame.

"I thought it was going to be easy. It's really tough," Odom, 31, tells Ellen DeGeneres in a new interview airing Tuesday.

Kardashian -- who also appears on her family's E! series Keeping Up With the Kardashians -- admits she tried to initially shield her husband from the pressures of being followed by cameras 24/7.

"I knew from doing my family's show how intense and grueling and how much they are really in your face," Kardashian, 26, says. "I personally didn't want to do the show. I love taping. I just didn't want to put Lamar through that pressure and Lamar was like, 'let's do it.'"

Consenting to the cameras was easier said than done for Odom, and three days into filming, he tried to quit.

"He said, 'Can you tell your mom to get us out of this contract?' I go, 'Absolutely not. That ship has sailed,'" Kardashian said.

While their already hectic life is no doubt made busier by having cameras around, Kardashian does see one major plus to taking part in the series, which airs its second episode Sunday.

"Lamar loves the finished product and we have really expensive home videos," Kardashian says.

"It's a little weird when it comes to [scheduling] sex," Odom says, as Kardashian, 26, and her BFF/assistant Malika go over the week's itinerary, which includes a book signing, dinner with Kardashian's mom Kris Jenner, and of course, lots of lovemaking.

While Odom is hesitant to plan their time in bed -- "I like to pop off spontaneously," he admits -- his wife is much more enthusiastic about the process.

"Wednesday, Thursday, Friday -- let's bang it out!" she enthuses.

Khloé: "I'm Not Desperate to Have a Baby"

Since marrying Lamar Odom in 2009, widespread pregnancy speculation has shadowed Khloé Kardashian and her non-existent "baby bump."

And although both Odom, 31, and Kardashian's brother Rob have said they hope there's a baby "on the way soon," Kardashian, 26, is in no rush to have kids.

"I'm not desperate to have a baby," the reality star told PEOPLE Thursday, while promoting her new E! show Khloé & Lamar, which debuts next month. "Do I want children? Yes. But I'm very happy being just Lamar and I."

She added, "I think a baby would add so much to us, but right now, I'm so content and so happy with the way things are. People think I would sell my hair to have a child."

That's not to say Kardashian would be upset if she got pregnant tomorrow.

"We feel like we're young and whatever is meant to happen is meant to happen," she says. "I'm healthy, I know I can have children. He can have children. It's like we're not doing anything to stop it, but I don't have like an ovulation calendar and all that."

Neither does she want to wait too long. "Trying to get pregnant is hard," she explains. "People don't seem to realize that you only have three days out of the month to get pregnant. And if you miss those three days, you have to wait for the next month."

Given all the variables, Kardashian says, "If I don't get pregnant in a few years, then we'll call the doctor and figure out what happened."
