'I like the chunkiness!' Kylie Jenner denies getting 'a** and boob implants' and credits her new curves to 16lb weight gain

Her changing figure is hard to miss.

But for anyone speculating about how Kylie Jenner achieved the womanly curves she so likes to flaunt on social media, she has a message.

 '[I haven’t had] ass implants,' the 19-year-old informed her dedicated fans in a Q&A on her paid-for blog. She also denied having surgery on other parts of her body, including her breasts, nose and jaw.

Kylie agreed she looked curvier - but blamed a 16lb weight gain for the change.

'You know, I used to be 120 [lbs.],' she explained. 'I was really skinny. Now I’m pushing like 136. But it’s alright, I like the chunkiness.' 

Thanks to the sultry pictures with which she entertains her social media followers, Kylie's changing figure hasn't gone unnoticed.

Fans have debated whether the teen has gone under the surgeon's knife - a rumour that has long dogged her big sister Kim.

Kylie dismissed such talk, explaining: 'I don’t really think I have the fattest ass, but I know my angles.'

But although she denied having had surgery, Kylie did not rule it out in the future, saying her breasts were 'not big'.

'I’ve thought about [getting breast implants], but I’m like, why ruin it?' she mused.

'I have really good boobs naturally and they’re a cute little size. I’m not against it, but right now, it’s a no from me.'

Along with her curvy rear and breasts, Kylie also discussed other parts of her body - and the speculation about them.

'People starting saying that [when] I was like 16,' she laughed.

'You think Kris Jenner, at 16 years old, would let me get cheek and jaw reconstructive surgery? Nah. 

'I always used to love my jaw – I never was self-conscious about my jaw.'

And of her nose she added: 'I didn’t get a nose job. I’ve always had a cute nose. I’ve really always liked my nose.'

Kylie has previously admitted using fillers to plump up her lips - something she at first denied.

The Keeping Up With the Kardashians star - who is dating rapper Tyga - was just 16 when she had injections to give her fuller lips.

She told complex magazine earlier this year: 'It has been an insecurity of mine all my life.

'This guy I kissed [in middle school] was like, "Your lips are really small but you're a really good kisser. I didn't think you were gonna be good at kissing."

'It was so rude. From then on, I just felt like I saw guys staring at my lips. I felt like no one wanted to kiss me.'

But Kylie admitted: 'I went too far. It was very painful.'
