In fact, the Blink-182 drummer just revealed when his wife is expected to give birth to their son.
"It's either Halloween," he said of Kourtney's due date while on the One Life One Chance podcast, "or like the first week of November."
During his chat with host Toby Morse, Travis also revealed they plan to name their baby boy Rocky.
The 47-year-old even joked about their son's "hard" name, saying Rocky is "gonna come out of my wife's vagina doing front kicks and pushups."
If the name sounds familiar, it's because Travis previously shared his interest in the moniker back in July.
As for the inspiration behind the name, Travis went on to share, "Rocky George played guitar for Suicidal Tendencies. And 13 is just the greatest number of all time."
And Kourtney agrees, considering they've settled on the name for their first child together. Rocky will join Travis' kids Alabama, 17, Landon Barker, 19, and stepdaughter Atiana De La Hoya, 24—who he shares with ex-wife Shanna Moakler—along with Kourtney's kids Mason, 13, Penelope, 11, and Reign, 8, who she co-parents with her ex, Scott Disick.
The growing family has even expressed their excitement over their soon-to-be baby brother.
"I just think having another family member is always awesome," Alabama told E! News during September's BeautyCon Los Angeles event. "Getting to know a new person, it's gonna be so fun and so exciting!"
