Kim Kardashian is a touch jealous of little sister Kendall Jenner’s appearance on the cover of Australian Miss Vogue, at just 17.

Kim Kardashian, 32, tweeted a photograph of Kendall Jenner from the shoot, alongside the post: “Kendall’s legs… I’m jealous!”

Kendall Jenner wears a pair of black hot pants, leather jacket and a velvet shirt in one shot, before changing into a backless black midi-dress with large hat and black high heels for another.

She wears the same outfit on the cover of the magazine as Miss Vogue’s third ever cover girl.

Kendall Jenner is clearly proud of her achievement, tweeting a link to the magazine’s website, and re-tweeting a post from the shoot’s photographer Russell James, who wrote: “Congrats @KendallJenner on your Ms VOGUE cover. Rare few models make it Vogue ever-especially by age 17!”

She also poses in a Gucci black hat with feather detail teamed with a black Burberry belted jumpsuit, and an orange patterned strapless swimsuit with floaty cream blouse.

Despite her envy, Kim Kardashian tweeted how proud she was of her younger half sister, posting: “The Miss Vogue shoot @kendalljenner shot is stunning.”

Kim Kardashian appeared in an equally striking shoot for L’Uomo Vogue back in July, with the black and white cover showing her sporting a short dark wig, oversized sunglasses and being besieged by photographers.

And her older sister Kourtney Kardashian was equally proud, tweeting: “I AM OBSESSED WITH YOU KENDALL! WOW. Breathtaking.”

It has certainly been an eventful week for Kendall Jenner who celebrated her 17th birthday with a party at the family’s Calabasas home.

The statuesque teen spent the evening skating hand-in-hand with actor friend Jaden Smith, 14, on the freshly frozen Kardashian family swimming pool.

Kendall Jenner blew out her candles on a cake bearing a childhood snap, while a drag queen MC presided over the Winter Wonderland festivities at her Los Angeles home.

The Keeping Up with the Kardashians starlet also sported goofy glasses for a silly photobooth and participated in a conga line on the ice with her friends.

However, it must have been hard for mother Kris Jenner to top the $90,000 Range Rover she reportedly gave Kendall for her sweet 16 last year.

Meanwhile, Kendall and Kylie Jenner were voted one of Zimbio‘s 2012 Most Influential Women Under 30 in TV, thanks to their fast-growing fame and combined seven million fans.

Kendall Jenner recently made her acting debut on a November 5 episode of Hawaii Five-0 on CBS.

The Jenner girls soon plan to launch their own clothing line, and they’re also penning their first sci-fi novel, due out next summer, with the help of co-writer Maya Sloane for publisher Karen Hunter at Simon & Schuster.
