Kylie Jenner has sparked speculation she's launching a new skincare line.

The lip kit guru has filed for a number of trademarks including 'Kylie Skin' and 'Kylie Skin by Kylie Jenner' - which is for goods that could include serums, scrubs, moisturisers, cleansers, toners, masks and oils - and another 'Kylie Skin' for retail store services "featuring skin care products, skin care preparation products, cosmetics, cosmetic preparations and gifts."

The filings at the United States Patent and Trademark Office are currently awaiting examination but could take from three months up to a year for processing - or she may decide not to pursue the filings.

Kylie was recently praised by her half-sibling Khloe Kardashian, 34, about her make-up know-how, admitting she has always received tips from the 'Life of Kylie' star.

She said: "Kylie is very confident, make-up is totally her world. I have learnt a lot from her.

"I am older than Kylie and she would say from a young age, 'You should really contour,' or make me change certain products I was using."

The 21-year-old mother-of-one revealed her 'In Love with the KoKo' collaboration with Khloe last month, and the 'Revenge Body' star has admitted that it was easy working with her sister as they "respect each other in their certain fields".

She said: "She just has such a great eye for other people's faces. When Kylie gives you a critique, it is coming from a helpful place; she's not trying to sabotage you in any way.

"She wants to pass on her knowledge on how to apply makeup. When we collaborated, it was super easy for her and I to work together. We respect each other in our certain fields and I think that is crucial for working with anyone."
