Barker shares children Atiana, 21, Landon, 17, and Alabama, 15, with ex-wife Moakler, whom he was married to from 2004 to 2008.

Meanwhile, Kardashian and her ex Scott Disick share three kids: sons Mason, 11, and Reign, 6, as well as 8-year-old daughter Penelope.

In January, a source said that Kardashian, 41, and Blink-182 drummer, 45, had been “dating for about a month or two,” adding that “they’ve been friends for a long time, but it’s turned romantic.”

“Travis has liked her for a while,” the insider shared.
