It was arguably the worst kept secret in Hollywood but fans were delighted when Kylie and Travis announced the birth of their daughter Stormi in February 2018.
"It's amazing how much Stormi has brought them together, and brought the entire family together with Kylie and Travis," a source told Us Weekly in June that year.
Speaking about Travis becoming a dad, Kylie said to Vogue Australia: “We both experienced this for the first time, so I love learning together and just watching him with her. He’s so good with her and she’s really obsessed with him.”
Travis also snuck in several references to Kylie in his Astroworld album and she even appeared in the music video for his song Stop Trying to Be God.

But less than two months after supporting Travis at the premiere of his Netflix documentary Travis Scott: Look Mom I Can Fly, in October 2019 Kylie confirmed that she had split with her baby daddy.
"Travis and i are on great terms and our main focus right now is Stormi," the makeup mogul wrote on Twitter. "our friendship and our daughter is priority."
The couple was then rumoured to be back on in March 2020 but it wasn't until May 2021 that an anonymous source told Entertainment Tonight: "Kylie and Travis are messing around and having fun together. They've always had a strong connection and chemistry and they're exploring their relationship romantically again."
In June 2021, it was officially back on: the family of three posed together on the red carpet when Travis was honoured at the 72nd annual Parsons Benefit as a "visionary" in "fashion, technology and the arts".
"Stormi, I love you and wifey, I love you," he said during his speech, according to E! News.
Kylie shared her own loved-up photo of herself and Travis, captioning it: "24 hours in NYC."
In honour of Father's Day 2021, Kylie penned a loving tribute to Travis alongside a candid family photo of them and Stormi that read: "happy father’s day @travisscott one day isn’t enough to honour the dad you are. we are so blessed to have you ..."
In August 2021, multiple sources confirmed to PEOPLE that Kylie was pregnant with her and Travis' second child.
According to WHO's sister publication, the mum-of-one is "enjoying her pregnancy in private" and is currently "a few months along."
