Kourtney Kardashian and new husband Travis Barker were married in Italy last Sunday, May 22, but while the couple have been celebrating, her ex Scott Disick is apparently struggling with "regret". Kourtney, 43, and Scott, 39, were together for nine years between 2006 and 2015. Together they share three children; Mason Dash Disick, 12, Reign Aston Disick, seven, and daughter Penelope Scotland Disick, nine.Their on-off romance ended due to Scott's "substance abuse" – as Kourtney revealed the reason behind their split during the Keeping Up With the Kardashians reunion episode in June 2021.
