New mother Kylie Jenner flaunts curvy figure in nude lingerie as she poses with sister Kourtney

The youngest Kardashian takes time out to pay tribute to her sister on her 39th birthday by announcing their latest collaboration under her Kylie brand with a sultry post of the two of them in barely-there lingerie.

Kourtney Kardashian received a ton of tributes on Wednesday as she celebrated her 39thbirthday but her sister Kylie Jenner also chose that day to announce their special collaboration for her cosmetics line, as reported by the Daily Mail.

Proud and excited over the fact that she was working with her older sister, the youngest Kardashian greeted her on her Instagram with the announcement of the birth of ‘KOURT X KYLIE’, the latest addition to her thriving cosmetics line that features three eye shadows and three lipsticks.

To magnify her announcement, Kylie posted a sultry photo of her and Kourtney posing in nude lingerie that’s certain to keep fans’ attention not just on her new line of cosmetics but on their scintillating bodies on full display.

She then drew attention to the real point of her post by promoting her latest make-up collection while paying tribute to her sister in her caption.

“HAPPY BIRTHDAY TO THE QUEEN! so excited to announce the KOURT X KYLIE collaboration...this collection gives me so much lifeeeee! 3 mini palettes & 3 of Kourtney’s signature lippies launching 4/24! collaborating with you was so much fun! I love you! Check out my stories to see our collab @kyliecosmetics p.s. we are both wearing one of her new shades RAD in this pic!”

After wowing her audience with their glowing bodies in their one-piece lingerie, she later posted snaps of the actual products she was selling on her Instagram Stories revealing glimpses from the line she created with love together with her sister.

Meanwhile, her sister shared in her excitement by posting a solo of herself from the same photo shoot and gushing over their latest collaboration.

“We have been working on this for a year...3 mini eyeshadow palettes and 3 lips..I am wearing Matcha on my eyes and RAD on my lips. Happy Birthday to me!”

There’s no reason why this new line won’t sell out in an instant with Kylie’s track record in the cosmetics business. She only launched her now billion-dollar cosmetics company in 2015 with her Kylie Lip Kits as her banner product. Now fully branched out into a full blown cosmetics line, the young entrepreneur is enjoying the fruits of her success. In June last year, she also collaborated with her sister Khloe for two cosmetic sets they called the KoKo collection.
