Kylie Jenner and her older sister Kendall definitely haven't had a normal upbringing. Growing up with cameras following their family's every move, and with a slew of business deals under their belts by the time they turned 16, the girls have definitely grown up fast.

But with 19-year-old Kendall now officially an adult and free to make her own decisions, Kylie is apparently very eager to follow suit. 

The 17-year-old has reportedly quit her at-home high school program without receiving a final qualification, in order to focus more on business projects such as her Pac-Sun clothes label (and her lip-liner addiction).

"Kylie quit homeschool a few months ago,” a source revealed to Life & Style magazine. “She told her mom it was getting in the way of her career, and that she wanted to focus her energies on building her personal brand and making money.”

The star's dad Bruce was reportedly "p**sed" with Kylie's rash decision, and the insider said he "blames Kris" for agreeing to let Kylie quit.

"Kris gave in," said the insider. "She feels the girls are smart and savvy and they don’t need a piece of paper to show that.”

Bruce has clashed with his daughter in recent months over the increasingly sexual selfies which she has been sharing on social media. "Bruce let Kylie have it after he saw that photo of her nipple ring posted,” a family insider said. “He told her that she is not an adult and needs to stop acting like she is some sex goddess.”

Poor Bruce – we reckon his words are going in one ear and out the other right now!

It can't be easy adjusting to the fact that your have parents have separated after 22 years' of marriage, but Kendall and Kylie Jenner seem to be handling things remarkably well.

The sisters have remained relatively silent about the split since the announcement was made last October, but yesterday they both took to social media amid revelations that their mum Kris had finally filed for divorce from husband Bruce Jenner.

Kendall posted a sweet throwback picture of her mum and dad together, with a heart emoji as the only caption.

Kylie, however, remained a little more indirect, sharing a cryptic quote with the caption "emptiness we created."

We hope the girls are doing okay and are being looked after by the Kardashian clan! Back when Kris and Bruce told their kids about the split on Keeping Up With the Kardashians, poor Kendall broke down on air, saying to Kim and co., "We won’t be siblings anymore … for someone to say we’re not going to be sisters anymore, that really really affects me.”

Yesterday it was revealed Kris has cited "irreconcilable differences" as the reason for the divorce, and Bruce reportedly made the same claim. 

The split seems to have been quite amicable, with the pair remaining on good terms. Back in April Kris even wished her ex a happy wedding anniversary, posting a picture with the caption "Happy Anniversary to one of the most amazing men I know!!!!! I love you, Wow 23 years!!!! #love #weareofficiallyvintage."

Kendall and Kylie are at least being kept busy this week by a number of other commitments. Kylie is involved in a fundraiser for Los Angeles Childrens' Hospital, while Kendall will most likely be walking the catwalks for Paris Fashion Week. Her mum flew out to join her yesterday, and posted this picture with the caption, "Well hello Paris I missed you!!!! #PFW #blessed"

Sounds like they're all doing okay so far!
