There’s no doubt both Khloe and Kim Kardashian have been working on their fitness in a big way during the last several months. But could the sisters’ weight loss be motivated by sibling rivalry? That’s the story according to the cover of this week’s Life & Style.

Emblazoned with a photo of Khloe looking white hot in a winter-white dress that does look like something her older sister Kim would wear, the magazine proclaims “I’m hotter than Kim now!” Inside, the article proclaims that “wearing that outfit was a total dig” at Kim. “Kim was always the skinny, pretty one — and now Khloe’s competing with her.”

Meanwhile, Kim who “always wants to be viewed as the hottest one,” is said to be “extremely jealous” of all the attention Khloe’s getting. However, a source close to the family tells Gossip Cop this is just the latest in a string of “ridiculous” stories about infighting in the tight-knit family.

Sure, these sisters can get competitive. What sisters don’t? But we find it highly doubtful that Khloe and Kim are doing anything but celebrating each other’s successes. They both are looking amazing these days, flirting with midriff-baring fashions that show off all their hard work in the gym and the kitchen. As far as we’re concerned, they’re all the hot one, including older sister Kourtney.
