Kourtney Kardashian and Travis Barker discover they're having a boy in incredible gender reveal video

Kourtney Kardashian and Travis Barker discover they're having a boy in incredible gender reveal video

The video was complete with an actual drum roll for full effect

Kourtney Kardashian and husband Travis Barker have revealed the sex of their baby in an incredible video, complete with drum roll and all.

It's only been a week since Kourtney sent fans' heads spinning with her shock pregnancy announcement, with the star rocking up to support her hubby's band Blink-182 donning a sign reading: "Travis I'm pregnant."

As the band took a break between songs, Travis' bandmates Tom DeLonge and Mark Hoppus spotted Kourtney in the crowd and called the drummer's attention to her sign.

The pair have revealed their baby's sex.

"We've got an announcement!" DeLonge called out at the gig, joking that the pair had been 'doing the dirty'.

"Let's hear it for Travis!" DeLonge continued. "He's going to have a baby!"

The dust has only just settled on all that, but the couple have wasted no time in sharing their gender reveal party with fans.

Kourtney surprised Travis with the news.

In the video, Kourtney can be seen sitting on Travis' lap as he does a literal drum roll - yes, really - building up to blue confetti shooting out behind them. They're having a boy!

This will be Kourtney's third son. She shares three kids with ex Scott Disick - sons Mason, 13, and Reign, 8, as well as daughter Penelope, 10.

Travis, meanwhile, has two kids from his previous relationship with ex-wife Shanna Moakler - 19-year-old Landon and 17-year-old Alabama. He is also stepdad to 24-year-old Atiana De La Hoya.

Fans flooded the video with comments following the news, with many noting how they've 'never seen [Kourtney] happier.'

The vid was complete with a drum roll for full effect.

"I love how in love they are! It's so much better in this world when two people are in love because they spread that joy to others... Congratulations Travis and Kourtney," gushed one fan.

"She has finally found happiness," wrote another.

Meanwhile, a third put: "She looks genuinely happy."

The pair's pregnancy update comes after Kourtney opened up on The Kardashians about her and Travis' struggles to conceive naturally.

It's a boy!

The pair have undergone IVF treatment, but in May said they were 'officially done' with that route.

“We would love a baby more than anything, but I just really believe in what God has in store for us. If that's a baby, then I believe that it will happen,” she said on the show.

The pair tied the knot in May last year at a glamorous ceremony in Italy, not long after their courthouse ceremony in California.
