Has 17-year-old Kylie Jenner had a boob job?

Those Kardashians and Jenners are VERY good at getting us to guess things about their bodies.

And Kylie Jenner has done an excellent job with this photo she posted to Instagram, captioned “secret project”.

So, has she had a boob job? Is that what Kylie’s secret project is? Answers on a post card.

We need to add that if Kylie has had a breast augmentation then she’s VERY young to have done so – just 17. A case of too much, too young, we reckon, but as of now, there’s no official comment on her boob job rumours.

Kylie’s been the subject of intense speculation about whether she’s had work done in the past – mainly on her infamously plump pout – but she puts that down to clever make up.

She told Cosmopolitan: “You guys have watched me grow up since I was nine. My face is going to get different. Now I know how to do my make-up, contour and everything.

The key message here is that Kylie is open to surgery, though we hope she’s not gone down that route at just 17.

We reckon Kylie’s just doing what we did when were teens – wearing about seven bras at once (oh, come one, it’s the oldest trick in the book). We hope so, anyway.

And people aren't just talking about Kylie's chest...
