Scott, 32, was pictured last week getting friendly with his ‘ex girlfriend’ Chloe Bartoli during a trip to France – and now it’s been reported that he’s gone off the radar.
Meanwhile Kourtney, 36, attempted to put on smile for their children, Mason, five, Penelope, two, and six-month-old Reign Aston while celebrating the fourth of July.
A source told HollywoodLife.com: “She was sad, upset and reserved all day. She knew all eyes were on her throughout the afternoon.
“Scott hasn’t been communicating with Kourtney and is completely unreachable. She can’t believe Scott left her on the Fourth of July. He isn’t making excuses like he normally does.”
Kourtney and Scott’s relationship has had its fair share of ups and downs, with him being admitted to rehab earlier this year for ‘alcohol problems’.
Kim and Khloe’s big sister is putting on a brave face, and shared some snaps on Instagram of her and Penelope having fun over the weekend.
The source added: “This is an absolute nightmare, and she’s a wreck over this. She hasn’t spoken to him in days. This is not how she wanted to spend her Fourth of July.
“She’s trying to stay strong for the kids but she is absolutely, completely devastated.”
