Scott Disick‘s world was rocked last weekend when he learned that Kourtney Kardashian, 42, had decided to elope in Las Vegas with her fiancé, Travis Barker, 46. However, it was not so much the fact that she got married (although, not legally) that bothered Scott so much. It was the fact that, 15 years ago, Kourtney almost walked down the aisle with Scott in Sin City. Because of this, a source close to Scott told HollywoodLife EXCLUSIVELY that Kourtney’s shotgun wedding was like a “gut punch” to the 38-year-old father of three.
