'Dammit Kylie!' Jenner admits she 'grew up too fast' as she shares photo from an old Keeping Up With The Kardashians episode

Kylie Jenner has admitted that she grew up too fast - albeit in a jokey Instagram post.

The 17-year-old shared a screenshot from an old episode of Keeping Up With The Kardashians, where she appears to be a few years younger.

'I promise I won't grow up too fast,' Kylie is telling her parents in the clip.

Update your denim in Kylie's 7 For All Mankind jeans

Kylie Jenner may only be 17 years old but she's got a wardrobe to die for and killer style to boot.

The teenager always looks great whether she's glammed up on the red carpet or kicking back with friends, and we love her eclectic take on fashion. She never makes the mistake of falling into an outfit rut.

She looks her best (and most age appropriate) when she's taking it easy in a California cool ensemble and this off duty look is great for a dressed down day. We love the slashed side tee but it's her jeans we're coveting.

They fit her like a glove and with their high waist they're super flattering, making her legs appear longer and clinging to her gorgeous curves. The rips at the knee keep things casual and of course distressing is still a major trend so she's as on point as ever.

This denim dream is by 7 For All Mankind and if you click (right) you can buy the exact pair at Neiman Marcus. Or recreate the look with our edit below.

The reality star acknowledged that she went back on her promise with the caption 'Dammit Kylie!' although she clearly finds it funny and added a crying with laughter emoji.

Kylie has certainly grown up quickly, having been in the spotlight on the show since she was just nine years old.

Nowadays, she is believed to be dating 25-year-old rapper Tyga, and recently purchased and moved into her own home.

In May, Kylie admitted after months of speculation that she has lip fillers, but she has denied rumours that she got breast implants.

The teen will celebrate her milestone 18th birthday next month, on August 10.

In the meantime, Kylie will be attending the ESPY Awards on Wednesday with her siblings, to support her dad Caitlyn Jenner.

The transgender Olympian, 65, is receiving the prestigious Arthur Ashe Courage Award at the event.

Over the weekend, Kylie found herself in the middle of an online feud with Hunger Games actress Amandla Stenberg, who accused her of appropriating black culture' without using her celebrity 'to help black Americans', after she shared a selfie with cornrows.

The 16-year-old commented on the snap: 'When u appropriate black features and culture but fail to use ur position of power to help black Americans by directing attention towards ur wigs instead of police brutality or racism #whitegirlsdoitbetter.'

Kylie responded: 'Mad if I don't, Mad if I do…. Go hang w Jaden or something.'

The Keeping Up With The Kardashians star was referring to the fact that Amandla, who rose to fame playing Rue in The Hunger Games, went to prom with Jaden Smith in May.

Justin Bieber later jumped to Kylie's defence and wrote on Instagram: 'Guys leave her alone, were all trying to figure it out and she happens to be under a microscope!' [sic]

The singer, 21, added: 'I'm the first to know this. But saying she's being racist because she has her hair in braids is ridiculous.

'Lets focus on the bigger picture and instead of fighting over something stupid lets do something about equality, but it doesn't start here blasting a 17 year-old kid for wearing braids.'
