Kendall Jenner may be collaborating with her sister Kylie Jenner for a new cosmetics line. While responding to a comment by a fan, Kylie teased that she may be working with her sister on a new project, but the details about the products they will be releasing together is a secret for now.

Kylie has already worked with her sisters and mother for her cosmetics company. The youngest self-made billionaire is now preparing to collaborate with Kendall for a new product line.

During a recent Instagram Live Video chat, Kylie was asked by a fan about whether she was going to work with Kendall, People reported. The reality TV star read the question out loud and responded by first winking at the camera, placing a finger on her lips and saying “shhh,” which implies that there is something in the works that is a secret.

The reason why Kylie has worked with all her other sisters and not Kendall is because the latter was under contract. However, the reality star said that she and her sister have “worked it out,” suggesting that they will be collaborating on a project soon.

Kylie was 15 and Kendall was 17 when they first collaborated on a project together back in 2013. The duo created a clothing line for PacSun at that time. They have also been successful with their own line of products under the Kendall + Kylie brand.

What is this new project that the sisters have been working on? Both Kylie and Kendall love designing new products. In a previous interview with WWD, Kendall, who is a model, explained that she liked to step back and watch another model try her designs while she played a more creative role in the project as the person behind it.

Meanwhile, Kylie continues to launch new products through her cosmetics company. She recently launched new lip kit shades, lipsticks and pan eyeshadow palettes.
