Kourtney Kardashian and Travis Barker's lives were already somewhat intertwined before they made their romance official in 2021, and later actually official when they tied the knot in 2022.
The Lemme founder and the Blink-182 drummer both lived with their respective children in neighboring Calabasas homes for years — he was a neighbor to the Kardashian family even before then — and the kids have since gone from neighbors to siblings.
They have also welcomed the addition of son Rocky 13, the couple's first child together, who was born last fall.
Below, get all of the details of Kourtney and Travis's blended family of seven children, Atiana, Landon, Alabama, Mason, Penelope, Reign, and Rocky.

Atiana, 25, is Travis' ex-wife Shanna Moakler's daughter with boxer Oscar De La Hoya. She was five years old when her mom married Travis in 2004, and the two have a tight-knit, father-daughter like relationship that has remained even after Travis and Shanna split in 2008.
