Kylie Jenner turns to Kourtney Kardashian when she needs advice.
The 18-year-old reality star is close to all her famous family members but thinks her oldest half-sibling is the best person to go to when she has a problem.
She said: "Kourtney probably gives the best life advice, but I go to my sisters for all advice and to each of them for different things."
When it comes to fashion and beauty, Kylie turns to Kim Kardashian West and her husband Kanye West for inspiration.
She said: "Kim really inspires my look - she inspires me the most.
"I think my sister and Kanye have great style and the people around them really inspire me."
However, the 'Keeping Up With the Kardashians' star is a big believer in "self-expression" rather than copying what is stylish or in fashion.
She added: "Other than that, I don't really have anyone I get inspiration from.
"I just like to be organic and be me. I'm really into self-expression and whoever I'm feeling that day."
This year, Kylie - who is dating rapper Tyga - has vowed to be more healthy.
Asked her New Year's resolutions, she told Look magazine: "Probably just to work out and be healthy.
"Maybe I'll get a treadmill in my house or something. I mean, I'll try to eat good and go on walks. Maybe do some hiking."
