The 24-year-old took to Instagram on Tuesday, September 7, to share the exciting news alongside a video that she captioned with a white heart emoji and pregnant woman emoji while tagging the rapper.
The video begins with the reality star holding a pregnancy test with a positive result before leading into a sweet moment with the 29-year-old embracing her stomach. Another shot features the family-of-three heading to a doctor's appointment before Jenner's OBGYN informs her during an ultrasound, "Honestly you're days away ... from a heartbeat" as the makeup mogul laughs.
In one moment from the clip, Stormi surprises Kris Jenner with a bunch of sonograms as the momager emotionally says, "This is one of the happiest days of my life!"
The video continues to document Jenner's second pregnancy, sharing behind-the-scenes moments from her 24th birthday in August, a stunning shot of the Kylie Cosmetics founder showing off her growing baby bump and a sweet moment of 3-year-old Stormi embracing her mother's bump.
Though the KUWTK star famously hid her first pregnancy, it seems Jenner is taking a different approach this time around. However, not everything is different: The melody from Jenner's pregnancy reveal is similar to the same song she used to announce she was a mommy in her "To Our Daughter" video she posted on her YouTube page in 2018.
Jenner and the "Sicko Mode" rapper artist started dating in April 2017 and split two years later. However, the two remained on friendly coparenting terms, continuing to make several red carpet appearances with Stormi. Most recently, Jenner shared a photo of Scott surprising their daughter with a school bus.
As OK! previously reported, just because Jenner and Scott are expanding their brood doesn't mean that they are officially back together, with a source dishing, "There’s a chance they’ll go back to being coparents instead of a couple."
