In case you missed it, last week, Kourtney announced she was pregnant in the audience of a Blink-182 concert. The 44-year-old reality star jumped up and down in the crowd with a sign that read, "Travis, I'm Pregnant."
It was a reference to the band's "All the Small Things" music video.
Now, the constantly-kissing couple incorporated music again to reveal future baby Barker's sex.
In a video shared on Instagram, Kourtney sat on Travis's lap as he started a drumroll before slamming the cymbals down. At the same time, blue confetti blasted into the air.
Congratulations. It's a boy!
Of course, the couple, all dressed in white, did what they do best to celebrate — they made out.
Both Kourtney and Travis have children from a previous relationship. Kourtney shares three kids, Mason, 13, Penelope, 10, and Reign, 8, with her ex Scott Disick. Travis has two kids, Landon, 19, and Alabama, 17, with his ex-wife, Shanna Moakler, and he looks after Atiana De La Hoya, 24, from Shanna's past relationship with Oscar De La Hoya.
