Kourtney Kardashian 'blindsided' by pictures of Scott Disick with other woman
Newly single Kourtney Kardashian was well aware of her partner's problems with partying - but was completely surprised to see him pictured with another woman.
Mum-of-three Kourtney (36) called time on their troubled relationship after pictures emerged of Scott (32) with another woman while on holiday in Monte Carlo.
Sources close to Disick say the father-of-three has been claiming he's "newly single" for the last month while he's been in Monte Carlo.
The former couple have had their issues - mainly Scott's partying - but it seems the final straw for Kourtney came when she saw him hanging out with a former girlfriend.
TMZ report that sources close to Kourtney and Scott say the Kardashian agreed to stick by the father of her three children as he battled issues with substance abuse. This was done mainly for the sake of their children.
Despite their rocky past, infidelity has never been an issue between them.
So when pictures emerged of Scott cuddling up to an old flame, stylist Chloe Bartoli, Kourtney was completely caught off-guard.
TMZ have reported that Kourtney has decided to put a permanent end to their relationship - also for the sake of their children.
Friends say Scott hasn't been at their Calabasas home in more than a month.
The couple have split before - the last time in 2010 - but reunited shortly afterwards.
Sources close to Kourtney say there is no going back this time.
The couple have three children together - son Mason (5), daughter Penelope (three) and ten-month old baby son Reign.
So far, Kourtney has stayed quiet about the split. She posted a picture showing herself and daughter Penelope celebrating US holiday Independence Day on Saturday.
Sisters Kim and Khloe have also kept quiet on their social media platforms.
Stepbrother Brody Jenner - son of Caitlyn Jenner - was surprised when he was questioned about their relationship when he appeared on the 'Today' programme in the US. He was on the programme to publicise his new series 'Sex With Brody'.
"When I saw those pictures I said, 'Uh-oh,'" Jenner told viewers. "I even showed my girlfriend and said, 'This isn't good.' But it's unfortunate."
"Scott and Kourtney both are great.
"Obviously Scott has gone through some issues in the past [but] he has worked through them."
