Kim Kardashian Jealous of Kendall Jenner's Sexy 'Miss Vogue' Cover: Did Kris Humphries Buy Girlfriend Myla Sinanaj Boob Job to Look More like Ex? [PHOTOS]

Stunning 17-year-old Kendall Jenner (one of the youngsters on E!'s infamous "Keeping Up with the Kardashians") graces the upcoming cover of "Miss Vogue" Australia in all her youthful sexiness. And sis Kim Kardashian is jealous - but not at all in the catty, diva-esque way that so many would assume! Kanye West's reality star sweetheart recently posted a Twitpic of her gorgeous younger sister from the "Miss Vogue" photo shoot exclaiming, "Kendall's legs... I'm jealous!" And in other Kim K news, did ex-hubby Kris Humpries invest in a boob job for his new girlfriend Myla Sinanaj so she'd look more like the Hollywood socialite? Read on for more details!

Kendall flaunts the cover of Australia's "Miss Vogue" cover in a sexy and chic backless black dress, proving that the first daughter of Kris Kardashian and Bruce Jenner is growing into one fine young lady! Check out some of the love she received from her famous older sisters on Monday (Nov. 26):

‏@KimKardashian: "So proud of @kendalljenner!!!! Cover of Miss Vogue... Kendall's legs... I'm jealous!"

‏@KhloeKardashian: "Wow!!! Show them how it's done @kendalljenner #Werrrkkkk"

@KourtneyKardash: "I AM OBSESSED WITH YOU KENDALL! WOW. Breathtaking."

@KimKardashian: "The Miss Vogue shoot @kendalljenner shot is stunning!"

It looks like Kendall has inherited her sisters' love for fashion! And younger sis 15-year-old Kylie Jenner seems to be working her way up the high-end fashion ladder too!

And as for the rumors that Kim K's ex-beau Kris Humphries actually bought his current girlfriend Myla Sinanaj breast implants in order for to look more like the curvaceous Hollywood starlet? According to one Hollywood Life inside source, it's most definitely true! "Kris paid for Myla's boob job because he's trying to turn her into Kim Kardashian... No one knows she got a boob job, but she went from a B cup to a D cup." The Kim K look-alike does closely resemble Humphries former wife of only 72 days (especially with her "enhanced" physical features)... so what do Mstarz readers think?
