Kylie Jenner has praised her ''unmatchable'' bond with best friend Jordyn Woods.

The 21-year-old reality star is set pair up with her longterm best pal to launch a special range of cosmetics through her Kylie Cosmetics brand, and has said she considers Jordyn to be a member of her ''family'' as she's stuck beside her through thick and thin.

Posting a professional snap of herself and Jordyn on Instagram, the 'Keeping Up with the Kardashians' star wrote: ''i can't wait to introduce the KYLIE X JORDYN @kyliecosmetics collection to you guys but before i do, i wanted to come on here and let you know just how special this collection really is to me. jordyn and i have had a true unmatchable relationship and i consider her family. she's helped me remain ME throughout all these years and this is the first time we have collaborated on such a project! it has been so much fun and I'll cherish the memories forever! we've worked hard on this and hope you love it as much as we do! reveal coming tomorrow (sic)''

And Jordyn took to her own account to share the same photo, where she dubbed the 'Life of Kylie' star as ''the most supportive friend''.

She wrote: ''Kylie Kylie Kylie !!! Our collab is finally here after all of the changes we've made to it over the past couple of years lol and I couldn't be more excited! Thank you being the most supportive friend and life partner! Reveal tomorrow @kyliecosmetics (sic)''

The pair's sweet words come after Jordyn, 20, recently revealed she felt inspired to start her own family by watching how Kylie has transformed into a mother since giving birth to her daughter Stormi - whom she has with Travis Scott - seven months ago.

Jordyn said: ''[Stormi] is great. She is so cute. I thought having her around would [make me nervous to have kids], but it's is actually inspiring me to have my own.

''But that's not happening anytime soon! [laughs] But [Stormi] is amazing.''
