So when she finally announced the news, fans realised that she and her big sister Khloe were actually pregnant together!
It was a pretty amazing experience for them, as it was both their first child. So naturally, they're pretty keen to be pregnant at the same time again.
Kylie and Travis Scott have had a pretty solid relationship since they begun dating. Despite the cheating hoax that a YouTuber pulled off last week, there hasn't been a bump in the road for these new parents. Since Kylie has taken to motehrhood so well, she has been very open about wanting more kids.
"Kylie and Travis are going to wait until he's finished his [Astroworld] tour before trying for another baby," a source told Entertainment Tonight. "They want to have another child soon so it's close in age to Stormi, but they do not want to do this while he's busy on the road."
As for Khloe, the entire world experienced her heartbreak when it was revealed that partner, and baby-daddy Tristan Thompson cheated on her, only days before Khloe went into labour with baby True.
Since the birth of their child, Khloe and Tristan have been working on their relationship, and now seem to be happier than ever.
"Now that she's a mum, Khloe's never been happier," a source told Entertainment Tonight. "She has wanted this baby more than anything and motherhood has proven to be even more incredible than she imagined."
Apparently, the couple is in "such a good place now" after spending Thanksgiving together last month. "Her relationship with Tristan is so good," said the source. "They made it through some really dark times, but she's happy that she gave him a second chance because he's stepped up and is not only an amazing father to True, but he's been such a rock for Khloe. They're really just so in love."
Since they're doing so well, Khloe wants to try for a second baby. Getting pregnant wasn't exactly easy, so Khloe is "aware it may take some time again," and doesn't want to wait too long.
The best part is that the sisters might actually plan their pregnancies together.
