The 33-year-old television personality has taken to social media to announce she is teaming up with her youngest half-sister, as the pair will be filming a "little YouTube" video in due course.

Alongside a picture of the 'Keeping Up With the Kardashians' stars, which was shared on Snapchat, the former 'Kocktails with Khloe' host said: "Filming a little YouTube with my twin!"

It is rumoured the pair will be discussing beauty tips on the site as they have previously teamed up to launch a make-up line named the Koko Kollection under Kylie's eponymous brand Kylie Cosmetics.

But the pair have kept the details of their joint venture close to their chest.

Khloe and Kylie are not only planning to film a video, but they are also believed to be experiencing their first pregnancy at the same time as one another.

Khloe is believed to be expecting her first child with her beau Tristan Thompson, whilst the 20-year-old beauty mogul is rumoured to be having her boyfriend Travis Scott.

And both Kylie and Khloe are keen to keep the exciting news private, as the youngest in the Kardashian/Jenner brood - who is known for sporting skimpy garments - has recently opted for looser outfits, which has sparked rumours she is trying to maintain a private personal life.
