Kendall Jenner collaborating with Kylie Jenner on cosmetics collection

Kendall and Kylie Jenner

Kendall Jenner is finally teaming up with her sister Kylie Jenner on a collection for Kylie Cosmetics.

Since she entered the cosmetics business in 2015, Kylie has collaborated on collections with her half-sisters Kim, Kourtney, and Khloe Kardashian, mother Kris Jenner, and more recently, her daughter Stormi, who is about to turn two years old, and now she's working with her sister Kendall on a line.

Ellen DeGeneres revealed the news while interviewing Kendall on The Ellen DeGeneres Show on Thursday, and the model explained her contract with Estee Lauder was the reason why she wasn't able to collaborate with Kylie Cosmetics before.

"And you're doing a make-up collab with Kylie as well, which is very cool," the talk show host said, to which Kendall replied, "Yes, we're very excited about it. We've actually not said anything, that we're doing it, yet.

"I'm the last sister - or the last family member - I think. I had a contract before with another make-up company, so now I'm able to do it."

The 24-year-old, who was wearing winged eyeliner, shimmery bronzer, and a mauve lip gloss on the show, also teased that she was wearing products from their collaboration. She added that they were both taking the line "seriously" and planning to go all out.

"I feel like we're really going big because I'm her full blood," Kendall said.

Kylie, 22, explained to fans during an Instagram Live last year that her sibling's Estee Lauder contract was the reason behind a delay in their partnership.

"You know Kendall was in a contract for a really long time, so I couldn't do a collab with her. That's the only reason why I didn't collab with her... But, you know, we worked it out," she shared.
