Meanwhile, the Blink-182 member's fit consisted of a white vest and black beanie as he sat in front of his drum set in the outside venue.

"Is our pyro guy ready?" he asked his wife. "I don't know what’s happening, whatever you guys had planned," she replied as sounds of a crowd out of shot were heard.

Then, a voice that sounded like the Kardashians star's sister, Khloé Kardashian, shouted, "Let's get the party started, we're all excited!"

Shortly after Travis did a brief drumroll and smooched Kourt, before striking the drum's symbols just as a burst of blue streamers shot into the air behind them, confirming that the couple is having a boy.

"I knew it!" another person shouted as Kourtney and Travis embraced and kissed while the crowd cheered.
