Kendall Jenner may be the one walking the runways during Fashion Week these days, but little sister Kylie wants to show off her beauty too. The 16-year-old reality TV starlet flaunted her bikini body on Instagram Wednesday, in a black bikini.

"So.. Is it summer ?" the "Keeping Up With The Kardashians" star wrote as the photo caption. Is Kylie trying to grab attention away from Kendall?

Kendall has been making quite a mark in the modeling world, and walked in Marc Jacobs' show in the recent New York Fashion Week. The 18-year-old celebutante has been signed since November to the Society Management, which also represents Liu Wen and Adriana Lima. Prior to that, she worked with Wilhelmina.

In October, the 18-year-old became the latest face of Agua Bendita’s swimsuit collection. She showed off her slim physique in an array of colorful bikinis and one-piece swimsuits for the Colombian swimwear brand's new campaign. She was in elite company in the shoot, alongside Candice Swanepoel, a top Victoria's Secret model.

If Kylie is jealous of Kendall, she is not alone. Reports have also claimed that older half-sister Kim is also envious that Kendall has a greater chance of getting into Vogue magazine than she does. Kendall has already appeared in Miss Vogue, and it is no secret that Kanye West, Kim’s fiancé, has been trying to get Kim on the cover of the coveted magazine for months now.

"There's no way Kim Kardashian shouldn't be on the cover of Vogue. She's like the most intriguing woman right now. She's got Barbara Walters calling her, like, every day," West told television personality Ryan Seacrest last October.
