While Scott Disick has seemingly fallen off the deep end, Kourtney Kardashian is leaning on her sisters and working up a sweat following their split. The reality star posted an Instagram of herself working out with sisters Kim and Khloe Kardashian on Tuesday, July 7, just one day after Us Weekly revealed she finally called it quits with the self-proclaimed Lord.

“Sister workout sesh this morning in the rain,” the newly single mom of three captioned the photo, in which she looks noticeably slimmed-down.

Kourtney has yet to directly reference the split, but sources tell Us she had finally had enough with her longtime partying boyfriend.

“She really has had it this time,” the insider said of the 36-year-old, who spent the Fourth of July with her kids while Disick, 32, was off cozying up to his ex-girlfriend Chloe Bartoli.

According to reports, Kourtney was blindsided by the photos of Disick getting uncomfortably close with Bartoli in the South of France.

"There was no trying to hide how handsy they were," an eyewitness previously told Us of Disick and the L.A.-based stylist, whom he dated prior to Kardashian. "They were all over each other and so blatant. They were feeding each other with their own forks. She was nuzzling her head on his shoulder, and he was stroking her arm and thighs."

“Kourtney is freaking out,” a third source revealed to Us. “She can’t believe he’d be so stupid to embarrass her and be photographed all over Chloe.”
