Kourtney Kardashian 'on the verge of a mental breakdown' over Scott Disick in KUWTK teaser

Kourtney Kardashian, we feel your pain.

The 36-year-old tearfully admits she's "on the verge of a mental breakdown" over ex Scott Disick's cheating scandal in a teaser for next week's Keeping Up With The Kardashians.

Her reaction has us feeling all emotional for poor Kourt. Watch above.

After the teaser aired, the mother of three thanked her 16.1 million followers for their support.

Back in July, Scott was caught cuddling up to his ex Chloe Bartoli on holiday in France, leading to his split with Kourtney.

This week, the 32-year-old was photographed with an 18-year-old model, Lindsay Vrckovnik, in the early hours of the morning while partying in LA.
