"Let's gooooo @travisbarker @blink182," the Good American founder captioned one of the clips. "I have no idea what is happening by the way. Living my best rock star life."
It was just a few days earlier that Kourtney first publicly revealed her pregnancy at a show. Footage from the special moment depicted the mom-of-three holding up a sign that read "TRAVIS I'M PREGNANT," which was a homage to an old Blink 182 music video.
Though Travis already knew about the pregnancy, he was surprised by his wife's gesture, and even got out of his seat to go into the crowd and give her a hug.
The couple, who tied the knot last year, had been trying for a baby for a while, documenting their failed IVF attempts on The Kardashians.
"It really took a toll on my health and mentally. The hormones. The medication. You have to get put to sleep every time," she explained of the struggles she endured with the process. "I know it's for so many people but it's just not for me."
Eventually, the couple decided to leave a pregnancy up to fate.
"I got to a place where I just felt exactly like how timing is everything with me and Travis ... So, I feel like if it's truly meant to be it will happen," explained the reality star.
