Its over - Kourtney calls it quits with Scott Disick after 9 years and three children

The couple have been together for 9 years but never married

Kourtney Kardashian has dumped her partner of nine years Scott Disick, it has emerged. The news comes four days after the 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, 5, 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.'

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.'  Dailymail
