Kylie Jenner suffers from low self-esteem.

The 'Keeping Up With The Kardashians' star may be known for her confident persona but the 17-year-old television personality has admitted she does find herself feeling low sometimes.

She said: ''I feel like I've heard the worst anyone can say about me over and over every day. So it's like my self-esteem definitely wasn't good at a point, I guess?

''But especially having the most beautiful sisters in the world ... I just try to find what makes me feel good and be as confident as possible.''

Despite admitting her stunning siblings can make her feel a little disheartened about her own self sometimes, she insists having sisters is the ''best'' and says she regularly relies on them for advice.

She added: ''Having sisters is the best. I have a different relationship with each of them.

''I go to Kim [Kardashian West] for fashion advice, Khloé [Kardashian] is always boy and family advice and Kourtney [Kardashian] is like another mother to me.''

And Kylie also revealed she enjoys being an aunt to Kim's 21-month-old daughter North and Kourtney's three children, Mason, five, Penelope, two and Reign, four months and is looking forward to having children herself one day.

She told Teen Vogue magazine: ''It's so fun being an aunt.

''When I look to the far future and decide to have kids, I need to have a million girls. Ten years from now - in 2025 - I hope I have a kid.''
