The Kardashian-Barkers are true rockstars.

Drum roll, please! Kourtney Kardashian and Travis Barker just revealed the sex of their baby.

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.

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.
