Suddenly, Kaitlynn seemed to be playing Yahtzee before giving birth.

She also shared black and white photos of her holding her newborn daughter shortly after giving birth and of Kristopher cradling their baby.

Later, she changed into a cream-colored cardigan and was seen smiling tenderly at her baby, who was holding her finger.

Last October, the couple announced they were expecting their second child by sharing a joint Instagram post showing off their baby bump.

“Girl,” Kaitlynn captioned the image, ending her sweet and simple announcement with a white heart emoji.

Her boyfriend is seen in the background of the shot taking Kaitlynn’s photo in the reflection of a mirror.

The image prominently featured her baby bump as she applied eyeliner in a mirror.

Dressed in nothing more than a gray bra and white jeans, the MTV star stepped to the side and showed off her growing midriff.

More heart emojis abounded in Carter’s comments section as he received congratulations and love from a bunch of his famous friends and some of his The Hills co-stars.

‘My God!!!!’ repeated mom-to-be Nicole Williams English, 34. “Congratulations!!”

This will be baby number 2 for the New Hampshire native as she continues to stray further and further from her party girl heyday as the globe-trotting love interest of 29-year-old pop star Miley Cyrus.

The couple’s whirlwind romance only lasted two months in 2019, but it was reportedly no fling, as Kaitlyn was rumored to have moved in with Miley before the end of their short-lived relationship.

Both Carter and Cyrus were coming off tumultuous marriages, with the “Wrecking Ball” singer splitting from actor Liam Hemsworth, 32, and Kaitlynn splitting with Brody Jenner, 39.

Carter and Jenner, a veteran of The Hills and the son of 73-year-old Caitlyn Jenner, never obtained a US marriage license after marrying in Indonesia. Since their 2018 marriage was not legally binding, the couple could easily drift apart when they went their separate ways in 2019.

Kaitlyn and Brody have remained on good terms since their amicable split. The Princes of Malibu alum wrote that his ex-wife would be “the best mom” after she posted an Instagram photo of her first child.

Kaitlynn and Brock celebrated the birth of their son Rowan last year in September.

The new mom shared a series of heartwarming photos on Instagram showing her bond with Rowan after bringing him home from the hospital.
