Why Scott Disick’s Keeping His Distance From Ex Kourtney Kardashian (Source)

Scott Disick knows what's best for him. Amid ex Kourtney Kardashian's pregnancy with now-husband Travis Barker, a source tells ET, the father of three has been 'very low key' and 'focusing on himself and his kids,' Mason, Penelope and Reign, whom he shares with Kourtney. The source adds that Scott tries to be as supportive of Kourtney as possible, but also knows that it's best to keep his distance, especially during a stressful time; Kourtney recently underwent urgent surgery she says saved her unborn child.
