Kylie Jenner hasn't worked out in two and a half years.

The 'Keeping Up With The Kardashians' star may have an enviable figure but she insists it's not the result of hours of slaving away at the gym.

She told InStyle magazine: ''I haven't worked out in two and a half years.

''I'm living out my youth, not doing any exercise and eating what I want, which is pretty bad.''

Despite not worrying too much about her weight, the 17-year-old television personality does feel like people are always ''judging'' her.

She said: ''I feel like this life comes with so many blessings but it's also just difficult. It's extremely difficult and you are growing and making mistakes and everyone is judging you. So, that is definitely hard but there are so many blessings that come along with it too...''

And sister Kendall, 19, has insisted growing up in the spotlight doesn't make the pair any different from ''normal'' teenage girls.

She added previously: ''I mean, we are normal people. We go through our normal emotional days or our hard, rough days... we are just like everyone else.

''I mean it's not much different from someone working and dealing with that or whatever... and I know we probably have some things that are different from the norm, I guess. But ... we are normal for the most part and we go through the same stuff.''
