Travis Barker is doing his best to get along with Scott Disick. \n\nThe Blink-182 drummer, 46 — who is currently engaged to Kourtney Kardashian — is reportedly trying to keep things civil with Disick, 38, amid his upcoming wedding to the Poosh founder."Travis is cordial with Scott," an insider spilled to Us Weekly. "He doesn't go around trash-talking [Scott] and would never be caught publicly dissing him because of Travis' relationship with the kids. \n\nThe Talentless founder and Kardashian, 42, called it quits on their on-and-off relationship in 2015. They share three children together: Mason, 12, Penelope, 9 and Reign, 7.According to the source, Barker "respects Scott as a father and respects that they are both in the kids' lives." \n\nThe musician also has two kids of his own: son Landon, 16, and daughter Alabama, 16, whom he shares with ex-wife Shanna Moakler.\n\nBarker reportedly "wouldn't step on Scott's toes as a father," the insider added, noting Barker "has a close bond with Kourtney's kids and loves the fact that his kids get along well with Kourtney's kids.""[Travis] loves Kourtney so much that he wouldn't want to cause any drama in Kourtney and Scott's coparenting relationship," the source continued, adding that Barker and Disick never "get into fights so no one has to play peacemaker." \n\nTRAVIS BARKER & KOURTNEY KARDASHIAN COMICALLY REACT TO A PARODY OF THEIR UPCOMING WEDDING\n\n"They don't spend a whole lot of time together — really just for the kids' activities, sometimes pick-ups/drop offs and if there's a big family celebration."While the rocker — who popped the question to Kardashian in October 2021 – might be able to keep the peace, the Flip It Like Disick star reportedly "can't stand being around" his baby mama's new man. \n\nAs OK! reported, a source previously insisted that Disick "despises Travis," and only puts up with him for the sake of his kids. "Scott adores his kids and would do anything to make them happy."Disick is still having a hard time accepting Kardashian's new relationship, as he "feels like Kourtney was the one that got away and [he] still can't wrap his head around the fact that they're getting married soon." \n\nKOURTNEY KARDASHIAN WAS 'NEVER OPPOSED' TO MARRIAGE BUT 'HER THOUGHTS DEFINITELY CHANGED' AFTER GETTING TOGETHER WITH TRAVIS BARKER, SOURCE SPILLS\n\n"He feels like he's not going to find someone like Kourtney," the source added at the time.
