She may not have Kim Kardashian's monstrous butt, but Kylie Jenner knows a thing or two about stealing the spotlight -- just look at those lips! Come to think of it, they're almost as plump as her big sister's booty...

The 17-year-old reality TV starlet attended the launch party for her Kylie Hair Kouture line of extensions in West Hollywood on Thursday night, and as if her suspiciously larger lips weren't enough to catch your attention, she showed some skin and rocked electric teal tresses. We actually kinda dig her hair color and the outfit is great, but let's stop and remember that she's a teenager -- and that her lips were half the size of this last year. What on earth could she have possibly done?! I mean, that's not just a generous application of lip liner, is it?

Meanwhile, Kim showed off her curves in a nude ensemble, and after her raunchy full-frontal spread for Paper Magazine, she didn't appear embarrassed at all. I mean, this is the gal who became famous for letting Ray J pound her on camera, so when you start your career in porn, a naked photo shoot is NBD, right?
