We wonder how Kourtney Kardashian reacted to Travis Barker letting these secrets slip.

During an appearance One Life One Chance podcast with Toby Morse, Travis revealed that Kourtney is due to give birth on Halloween or within the first week of November.

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

Host Toby chimed in: “Rocky Thirteen Barker,” to which Travis confirmed: “Rocky Thirteen Barker!”

"That’s such a hard name man," Toby continued. Travis joked: “He’s gonna come out of my wife’s vagina like doing front kicks and push-ups…”

Toby said: “That’s such a great name,” to which the Blink-182 drummer replied: “Thank you!”

Though Kourtney might be a bit annoyed that the info is out, no doubt with her due date so near she's got bigger things on her mind right now.

It's been a tough pregnancy for the reality star as she had go undergo emergency foetal surgery last month that saved her unborn baby’s life.

Speaking to Vogue, the eldest Kardashian sister says the surgery completely shifted her perspective on pregnancy.

“That experience opened my eyes to a whole new world of pregnancy that I didn’t know about in the past. It was terrifying. After, I learned that insurance typically only covers two ultrasounds when you’re pregnant, I had no idea.

“I’ve always been lucky enough to do more than what insurance covers, and it’s one of those ultrasounds that saved my baby’s life.”
