First, Kris dodged the question when asked by reporters at fashion week, before texting Ryan Seacrest saying: "Kylie's not confirming anything."
Now, Kylie's big sister Kim Kardashian has broken her silence, taking to Twitter to call out fake news.
Reposting an article which alluded to her not being happy about her younger sister's pregnancy, Kim wrote: "This sounds like a very fake story..."
She then Tweeted saying that Caitlyn hadn't spoken to anyone about his daughter.
While it's not an official confirmation from the 36-year-old, she's doing nothing to deny the pregnancy articles (which, if they weren't true, would be in the same 'fake news' bandwagon.)
