“Is our pyro guy ready?” theBlink-182drummer asked his wife. “I don’t know what’s happening, whatever you guys had planned…” Kourtney replied, as sounds of a crowd out of shot were heard.

Shortly after, Barker began a drumroll and he kissed his wife, before striking the drum’s symbols just as a burst of blue streamers shot in the air behind them, confirming that the couple are having a boy.

“I knew it!” someone was heard shouting in the crowd. As the camera panned back to Kourtney and Travis, the parents-to-be embraced and kissed as the crowd cheered.
