Kourtney Kardashian and Travis Barker’s son’s name and birthday officially confirmed by birth certificate

Rocky's official day of birth was November 1, 2023, at Cedars-Sinai Medical Center in Los Angeles.

It would be several more days before Kourtney and Travis shared the news with the world.

DELIVERY DAY

On November 4, news broke that Kourtney gave birth to her and Travis' baby boy.

While Kourtney had not confirmed her exact due date, online reports claimed that the baby would come the week of Halloween.

This estimation was based on when she publicly announced her pregnancy.

Rocky is the couple's first child together, but each of the stars has children from previous relationships.

Travis welcomed son Landon and daughter Alabama during his first marriage to Shanna Moakler, while Kourtney welcomed Mason, Penelope, and Reign with her ex Scott Disick.

"I love the idea of a blended family. I think that the more kids, the merrier," Kourtney previously said during the Season 2 finale of The Kardashians, via .

"You have all these siblings and more people to love. It's a beautiful thing."

NAME GAME

Just days before Kourtney gave birth, Travis spilled their baby's name on friend Toby Morse's podcast, One Life One Chance.

While talking, he let slip that - as fans predicted - he and Kourtney were expecting a Halloween baby, and that he would be called Rocky.

Travis said: "There was a benefit in Hawaii that we were gonna do, but it’s the week that Rocky’s due."

Toby asked: "Rocky Thirteen Barker?" with Travis confirming: "Rocky Thirteen Barker!"

When Toby commented on the uniqueness of the name, Travis quipped: "He’s gonna come out of my wife’s vagina like doing front kicks and push-ups."

In July, Travis first hinted he would name his son Rocky 13.

The rocker talked about potential baby names with his daughter Alabama while appearing on .

The pair were asked what the "greatest of all time baby name" would be.

Alabama, 17, piped up first with her answers, saying: "Audemar, Milan, Patek."

Travis replied: "I like Rocky 13. That's this name that's just been going through my head lately."

Alabama shot the idea down, saying the moniker was "so bad."

"It is bad," Travis admitted, adding: "Rocky George played guitar for Suicidal Tendencies and 13 is just the greatest number of all time."
