Rocky's arrival was first reported a few days after his birth, but the chatter that Kourtney and Travis had already welcomed their son initially started after Kylie Jenner was spotted going to Cedars-Sinai hospital in LA.

The couple were seen leaving the hospital with their son about a week later, yet it's reported sis Kim Kardashian hasn't met Rocky yet.

It's been quite the journey since Kourt announced her pregnancy at a Blink-182 show last year.

While Kourt wasn't shy about flashing her bump, she did an undergo urgent fetal surgery to save their son's life.

Thankfully, everything seems to have worked for Kravis and baby Rocky, as he joins the Kardashian crew.
