Kim Kardashian is not the only Kardashian sister with impressive curves. Khloe is starting to give Kim a run for her money, prompting rumors that she got butt implants. Fans of the Kardashians have noted recently that the youngest sister has been looking phenomenal lately after getting more fit in recent months.

“I’ve definitely become obsessed with working out!" Kloe said in Cosmopolitan’s February issue. "It’s funny, because my weight has always fluctuated, but recently so many people have been saying, ‘You look so good, you’ve lost all this weight.’ It’s actually been about a year and a half that I’ve been making a lifestyle change. There’s no quick fix, I would say.” 

While Khloe, 29, may have lost weight, to many observers, it seems like she gained weight in her backside. During a dinner date this week with rumored boyfriend French Montana, her curves looked more voluptuous than ever. However, a source close to her says the rumor is not true, and that she does not have implants, Rumor Fix reported.

Recently, Kim received the same criticism, and in 2011, she defended her famous derrière by getting a butt X-Ray on her reality TV show to prove that it wasn't enhanced with injections. In November, she went on a Twitter rant denying that she had surgery to lose her baby weight. 

"I worked so hard to train myself to eat right & healthy, I worked out so hard & this was such a challenge for me but I did it!!!," Kim tweeted at the time. "I'm so proud of my accomplishment & NO ONE will take this away from me with fake reports!"
