It was only a few weeks ago that a source admitted to People that Kylie Jenner and Travis Scott were expecting their second child together (opens in new tab).

A source later told "Us Weekly" magazine (opens in new tab) that they have long wanted a younger sibling for Stormi Webster (opens in new tab) and had been trying to conceive for several months.

Now it is clear that Jenner and Scott could not be more thrilled. Jenner had not yet mentioned the pregnancy rumors, but is more than happy on that front.

On her Instagram page (opens in new tab), the 24-year-old Kardashian-Jenner's youngest sibling posted a 90-second video announcement of her happy news.

Set to sentimental piano music, the video begins with a shot of a positive pregnancy test, followed by Scott hugging Jenner's belly. The couple then puts Stormi in the back seat of the car, and Jenner asks her daughter, "Are you ready to go to the doctor, mommy?" She asks. The doctor tells Jenner, "Honestly, it's just a few more days, a couple of days, until the heartbeat," and the mom-to-be laughs giddily. Scott grins for the camera.

The next scene shows Stormi handing the scanned image in an envelope to Kris Jenner.

Happy family at home, at a restaurant, at the doctor's office ...... There are other scenes of happy families enjoying happy family time together. Jenner poses repeatedly for artistic baby bump shots and Stormy kisses her belly.

The congratulations from the couple's famous family and friends were immediate. Kendall Jenner said, "I can't handle it." 'I keep crying,' wrote Kris Jenner. 'I'm crying ...... So beautiful, my blessed angelic sister," tweeted Kourtney Kardashian (opens in new tab). Gigi (opens in new tab) and Bella Hadid (opens in new tab) and Hailey Bieber (opens in new tab) also offered their heartfelt congratulations.

Jenner also re-shared her congratulations on her Instagram Stories. Kim Kardashian (opens in new tab) wrote, "OMGGGG more babies !!!! More cousins !!!! Congrats @kyliejenner & @travisscott," she wrote.
