Kourtney Kardashian and Scott Disick

Kourtney Kardashian admitted ex-partner Scott Disick's battle with addiction was "a deal-breaker".

Asked by TV host Andy Cohen if they'd have stayed together if their lives were not so public, she replied: "Probably but I think the substance abuse was a deal-breaker."

Scott then admitted: "I was pretty irresponsible."

The pair co-parent their three kids Mason, 12, Penelope, nine, and Reign, seven.

Kourtney recently tied the knot with Blink-182 drummer Travis Barker.
