And it seems she's getting her life in order quickly as, according to United States reports, she's already planning an "amazing" wedding to take place as soon as she's lost her baby weight.
Reports had surfaced earlier in the day that suggested Caitlyn had only found out about the pregnancy online like everyone else, with a source telling Hollywood Life, "Caitlyn was really shocked and disappointed to learn that Kylie is pregnant".
I'm over here deciding if I can spring for an extra topping on my pizza and Kylie Jenner is making some huge life changes with Travis Scott. "Kylie Jenner is actually pregnant and we can all expect a baby clothing line and a bunch of adorable Instagram uploads at some point in 2018". Then, he discovered Kris Jenner had sent him a message about the supposed pregnancy, and excitedly revealed "Kylie's not confirming anything". If Jenner is having a girl, she will be over-the-moon excited.
"Kris says Kylie's not confirming anything", the host revealed on Monday. "She tries to keep it separate and doesn't want to discuss it with the rest of the family".
"It wouldn't be the family if something didn't happen every single day", she said.
The pregnancy revelation about Kylie Jenner came on Sunday, just before the special episode of "Keeping Up with the Kardashians".
Meanwhile make-up mogul Kylie is yet to officially comment on her impending motherhood, instead dropping several clues on social media that she could be with child.
OK! Online has contacted Caitlyn's reps for a comment.
"I needed to get on here instantly to let you know directly from me that Kylie Jenner is 99 percent pregnant", he said.
