Kylie Jenner hasn't worked out for two years.

The 'Keeping Up with the Kardashians' star has confessed she's been steering clear of the gym but wants to get back into exercising as she fears she could start piling on the pounds as she gets older.

She said: ''I haven't worked out a day in my life for like two years. It's really bad.

''I'm going to start this month, I need to for health reasons. I feel like all the food I eat is catching up with me as I get older.''

The brunette beauty, 17, also admitted she is ''intimidated'' by the constant pressure she feels to look good all the time.

She said: ''I am definitely conscious of it. It is a little intimidating to look good all the time, but I just try to make outfits and meet with my stylist [Monica Rose].

''We will just talk and collaborate. We will throw ideas around and talk about the stuff that we like. So it's really cool.''

And when she isn't working with her stylist, Kylie is taking fashion tips from her 20-month-old niece, North.

She said of the tot - who is the daughter of her half-sister Kim Kardashian West and her husband Kanye West: ''I love Kim and Kanye's style. North inspires me the most.

''Kim is always in the latest new stuff, so I always look to her for advice.''
