Business as usual! Kylie Jenner posts a sultry selfie to promote her new website...as it's revealed sister Kourtney Kardashian has dumped partner Scott Disick

The Kardashian/Jenner clan was rocked by drama on Monday after it emerged that Kourtney Kardashian had dumped her partner of nine years Scott Disick.

However, even the breakdown of a long-term relationship can't stop the clan posting selfies and youngest sister Kylie Jenner, 17, took to Instagram to share a snap and promote her new venture, a website. 

Kylie captioned the sultry selfie: 'can't wait to release all my beauty secrets coming soon. Love this bright look.'

Meanwhile, the news of Kourtney's split from Scott came four days after DailyMail.com exclusively revealed the father-of-three was getting very cosy with fashion stylist Chloe Bartoli in Monte Carlo.

The reality star, 36, is understood to have become tired of her boyfriend's endless partying.

And the photographs of him caressing Bartoli, who is said to be an old flame, were the last straw. 

'It's humiliating and disrespectful,' a source says of the pictures.

The pair have three children together; son Mason, five, daughter Penelope, who turns three on Wednesday, and baby boy Reign, who is six months old. 

Lord Disick, as he refers to himself, has not been home in a month and Kourtney has had enough, TMZ reports. 

A source told the gossip website: 'His partying lately has made her make this tough decision.'

It's all over: Kourtney Kardashian and Scott Disick, who have children Mason, Penelope and Reign (not pictured), have reportedly split after nine years together

Kourtney is said to be frustrated with his circle of friends, whom she believes is enabling his partying and substance abuse.

Another source tells E!: 'Kourtney has always taken Scott back and been by his side, but now with three kids it has gotten old. Kourtney has to do what's best for the kids.' 

'Scott has been running around saying he's single,' added the insider.

'Kourtney dumped him after she saw the pics [in Monte Carlo] and he hasn't been home after a month-long party binge.' 

DailyMail.com has contacted reps for Kourtney Kardashian for comment. 

Scott, 32, and Bartoli have now been photographed together over a number of days and were spotted stroking each other while Chloe was seen feeding the reality star on a number of occasions.

The stylist appeared to be quite smitten with the reality star and was even seen lounging on the same pool chair as him. 

Kourtney has yet to publicly comment on the pictures or news of the split.

It has already been a trying time for the couple, as Scott has continued to fight his alcohol demons.

Last month - despite a recent stint in rehab - Scott arrived at a nightclub in Montreal so inebriated he was unable to be introduced to fans.

To make matters worse, the event was held to raise money for the ONEXONE $1 Feed a Child Campaign.

Scott has already spent time at controversial Costa Rican rehab centre Rythmia Life Advancement Centre - he checked in in March.

While Scott was busy partying in Las Vegas last month, Kourtney took their two eldest children, Mason and Penelope, to the Universal Studios theme park in California.

Scott has certainly expressed his struggle with being a devoted family man on their reality show Keeping Up With The Kardashians.

In fact, last year, Scott went so far as to say Kourtney had kept 'suckering him' into having children.

In an episode last season, Scott was seen reacting badly when Kourtney broke the news that she was expecting their third child together.

'How many clothes does one little kid need?' he asked.

'A lot,' she answered. 'Can you shut the door for a second? I just wanted to tell you that I am pregnant,' she said with a coy smile.

Ominous music played, and Scott was so stunned he was lost for words.

'You just keep suckering me into these kids. I can't handle all of this responsibility,' said the seemingly unimpressed self styled 'Lord Disick.'

He added: 'Were you gonna wait 'til the kid popped out of ya?'

'I was not planning this. Responsibility for what? You have two children,' replied Kourtney.

'I just can't take care of more kids,' said Scott.

If that wasn't bad enough, it was revealed on Kourtney and Khloe Take the Hamptons late last year that the pair have been sleeping in separate bedrooms.

Kourtney and Scott met at Joe Francis' house party in Mexico in 2006. They briefly split in 2010 reportedly due to Scott's problems with drinking.
