Khloe Kardashian Defends Body Amid Surgery Speculation

Khloe Kardashian is defending herself against claims that she has a fake posterior. Kardashian, the 29-year-old "Keeping Up With The Kardashians" star, attended the 2014 NBC Universal Upfronts to promote her E! show with her sister Kim. After pictures of Kardashian in her form fitting black skirt made waves online, some questioned if she enhanced the lower part of her body.

When the rumors began to take form, Khloe defended her body.

"Sorry 2disappoint.... I've always had an (expletive)," she tweeted. "I know its more fun 2believe its not real, kind of a compliment since I kill myself in the gym (SIC)."

Khloe has a strict fitness and diet regimen, according to her celebrity trainer Gunnar Peterson.

"Khloé works so hard. She's killing it in the gym," Peterson told E! last month. "There are no shortcuts."

He went on to detail her workouts.

"You get definition from repetition…that includes repetition in the act of going to the gym," Gunnar told E!. "Khloé comes in three, four, five times a week, and that's someone who has an incredibly demanding schedule."

Kardashian said her mission earlier this year was to wear a midriff baring top, something she has achieved multiple times.

"My 2014 mission is to wear a crop top with jeans," told British Cosmopolitan as the February cover girl. "I've never done that so it has to happen one day."

Kardashian previously had naysayers when it came to her weight, but she learned to take the criticism in stride.

"I want to say I don't care, but of course [comments about my body] are going to sting," Kardashian told Cosmo U.K. last year. "I have to do whatever is good for me… I feel that I'm healthier [now], but I don't think I'm prettier thinner."
