Stealing Kim's thunder: Kylie Jenner, 17, strips to flaunt tan

And despite living in a pad with her own pool where she could sunbathe all day, Kim Kardashian's little sister has been playing safe by topping up her tan with a little help from the bottle.

The 17-year-old – who acts more like a twentysomething with her pierced nipple and 25-year-old rapper beau – posed in her underwear for a snap seeming to plug a range of fake bake products.

And while most kids are cramming for their exams in rooms Blu-Tack'd with 1D, our Kylizzle showed off her sophisticated pad with plumped pillows and mirrored bed frames.

There was just one thing stopping Caitlyn Jenner's daughter from looking 100% bronzed, however – she appeared to have missed a spot on her left leg which was distinctively streaky.

We kinda like it though. Reminds us of Katie Price's garter thigh tatt.
