Kendall Jenner is ''old-fashioned'' when it comes to dating.

The 20-year-old model - who has been linked to Harry Styles, Jordan Clarkson and A$AP Rocky - likes to be pursued and for men to make the effort to ask her out.

She explained in a new post on her website ''It's not that I'm scared of asking a guy out or showing him that I like him, it's just that I'd much rather be pursued. I definitely like the chase and the feeling of being wanted. And, the way I see it, if a guy isn't going to put in the effort and ask me out, then the relationship probably won't work. It would be a waste of time for me. Call me a little old-fashioned, but it's just what I like!''

Kendall also admitted that she panicked when she recently found her first grey hair.

She said: ''A couple months ago, I found a gray hair on my head. Even though I was jokingly being dramatic about getting one (they can be from stress!), it honestly does kind of freak me out. When I turned 20, I was scared, as crazy as that sounds. I just didn't feel ready to be out of my teens, yet - I didn't want to be in my twenties. I feel like your twenties are when you actually have to grow up and be an adult, which is scary!''

However, Kendall isn't quite ready to act mature all the time and likes to ''be silly and goof off''.

She explained: ''Because of my life and my job, I think I had to grow up pretty quickly but I've always tried to keep any bit of my ''kid life'' that I can. It's so important for me to be silly and goof off because I think that's what keeps people feeling young - whether they're 20 or 60.''
