The 29-year-old has recently slimmed down but she says it is not a compliment if it comes at the expense of her siblings Kim, who is pregnant with her first child, and mother-of-two Kourtney, reported Contactmusic.
"I am sorry but I do not find it a compliment when I am told I am 'the hot sister'. I appreciate the compliment but this is not a competition. We are sisters and women need to stop being compared to other women! Beauty is not how we look, it is how we act (sic)," Khloe posted on twitter.
"After my father died (in 2003), I gained a lot of weight, and then I was in the spotlight. I was quickly blasted for not being a cookie-cutter sister like Kourtney and Kim. I understand why so many people in this industry have eating disorders or want plastic surgery, and I'm proud I've done things the healthy way," she said.
