The 'Keeping Up With the Kardashians' star has applied to trademark several possible brand names as she prepares to launch her own line of make-up.

According to TMZ, Khloe, 33, has applied for the trademark on 'KOKO Kollection by Khloe Kardashian', as well as 'KOKO Kollection'.

Her sisters Kim Kardashian West and Kylie Jenner already have their own cosmetics brands and it was recently revealed Kourtney is also lining up her own brand, under the name 'Kourt'.

Kylie, 20 - the daughter of Kris Jenner and Caitlyn Jenner - launched her range in 2015 and has reportedly earned $420 million in retail sales in 18 months.

The range - called Kylie Cosmetics - keeps expanding year on year but is known for liquid lipsticks, lip liners, eye-shadow palettes, concealers and foundation.

Kim, 37, launched her KKW beauty range in 2016 and just two months ago dropped a line of shimmering highlighters and lip glosses.

Her perfume collection KKW Fragrance - called Crystal Gardenia, Crystal Gardenia Citrus and Crystal Gardenia Oud - sold out in just six days.

Khloe is currently expecting her first child with her boyfriend Tristan Thompson.

The reality star and her NBA star beau, 26, aren't planning on keeping the sex of their child a surprise either, so they can plan their baby's name as soon as they know what they're having.

When asked if she would be finding out the sex before the birth, Khloe said: "Yeah. There's too many surprises in this whole thing, so I'm definitely going to know."
