Kourtney Kardashian Brings Up Scott Disick's 'Substance Abuse' in 'KUWTK' Reunion Teaser - Watch Now

Andy Cohen is asking the Kardashian-Jenner family the hard questions.

E! released the teaser trailer for the upcoming two-part Keeping Up with the Kardashians reunion hosted by Andy, and nothing is off limits.

In the teaser, Andy sits down with Kim, Kourtney, Khloe, Kris, Kendall, and Kylie to talk about some of the biggest moments in their lives, which were all featured on their reality show.

At one point, Scott Disick joins the family on the couch and Andy asks Kourtney if their relationship “might have turned out differently” if the couple hadn’t “shared so much of it” on TV.

Kourtney surprisingly responds, “Probably” before adding, “But I think the substance abuse was the deal-breaker.”

Scott agrees with Kourtney, responding, “I was pretty irresponsible.”

Kourtney and Scott dated on and off from 2006 before splitting for good in 2015. Throughout KUWTK, Scott‘s battle with addiction often took center stage – between his drunken tirades and rehab stints.

At the end of the teaser, Andy asks Scott if Kourtney and new boyfriend Travis Barker‘s relationship has his “blessing.”

Part 1 of the Keeping Up With the Kardashians reunion airs on E! Thursday, June 17, at 8 p.m. ET.
