Kourtney Kardashian and Travis Barker are jumping into their happily ever after! The newlyweds held hands as they jumped off a yacht on Monday in Portofino, Italy. In the photographs, the pair was seen kissing on the boat before they climbed into the upper level of the yacht and jumped off together, hand-in-hand. The couple's fun outing comes one day after they tied the knot in Portofino on Sunday, one week after their legal ceremony at a Santa Barbara, Calif. courthouse. All of Kourtney's sisters – Kim and Khloe Kardashian, and Kylie and Kendall Jenner – were in attendance, as well as their mom, Kris Jenner, but one member of the family who wasn't spotted—Rob Kardashian. Kourt's younger brother was noticeably absent from footage shared via social media from the wedding and he wasn't photographed in any of the events leading up to the big day.
