Kris Jenner Can't Wait to Meet 13th Grandchild after Kourtney Kardashian's Dramatic Gender Reveal

"I can’t wait to meet this beautiful new grandchild!! What a blessing!!!!!! #luckynumber13!!!!!" Kris wrote alongside a re-share of the original video. "Congratulations Travis and Kourt!!"

Khloe shared her excitement, as well, commenting with a series of enthusiastic emojis on the original post.

Jenner's share comes a day after the newlyweds, dressed all in white, set up Barker's drum kit outside to share the big news. With the family shouting enthusiastically around them -- "Lets get the party started; we're all excited!" -- the pair locked lips (of course) and Travis kicked off a drum roll.

At the climax, nearby cannons shot off blue streamers as the couple embraced and kissed some more. The public gender reveal follows their public pregnancy reveal at a Blink-182 concert last weekend.

There, Kourtney was filmed in the crowd holding up a sign to the band reading, "Travis I'm Pregnant." Of course, there was plenty of kissing then, too, as it appears Travis may have truly not known she was expecting, per TMZ, despite her visible baby bump.

The day before the gender reveal, Kourtney was showing off the growing life within her in a green, string bikini shared as part of a carousel of photos on Instagram.

"sweet summer 🥝🥑🍐🥭," the Poosh founder captioned her post, which also included photos of her a few of her kids playing in a pool.

It was a week ago that she first debuted her bump in another carousel of sweet pics of her and Travis celebrating the news after she told him -- at least, she's wearing the same bodysuit and leather pants from the concert.

This son marks the seventh addition to her and Travis' large shared family. Kourtney shares three with Scott Disick -- Mason, 13, Penelope, 10, and Reign, 8 -- while Travis shares Landon, 19, and Alabama, 17, with Shanna, as well as stepdaughter Atiana, 24.
