Kourtney Kardashian in tears over Scott Disick cheating rumours in new KUWTK Trailer

This has been an eventful year for Kourtney Kardashian. After giving birth to new baby Reign Ashton Disick and dealing with step-dad Caitlyn Jenner’s transition, her relationship with baby daddy Scott Disick ended amidst nasty cheating rumours.

It finally got to be too much for the eldest Kardashian sister, who burst into tears in a rare display of emotion during the preview for season 11 of Keeping Up With the Kardashians.

Watch above as the 35-year-old mother of three breaks down after viewing some compromising photos of Scott, 32, and his his ex-girlfriend Chloe Bartoli, 25, in the South of France.

That story broke in June, and Kourtney and Scott split up soon after, with a source telling Us magazine that, "She really has had it this time…She can’t believe he’d be so stupid to embarrass her and be photographed all over Chloe."

If her Instagram posts are anything to go by, Kourtney appears to be recovering nicely. She's been working out, spending time friends and umm...taking out some anger on the shooting range?
