Conspiracy theories are swirling Kylie Jenner is Kim Kardashian's surrogate

Over the weekend it was announced that Kylie Jenner is expecting her first child with boyfriend Travis Scott.

So, of course, the internet has blown up with people speculating that she is actually the surrogate for her sister, Kim Kardashian.

Reality star Kim and her husband Kanye West turned to surrogacy after the 38-year-old had high-risk pregnancies with daughter North, 4, and son Saint, 21 months.

The surrogate is reportedly expected to give birth in January 2018.

However, an insider told Us Weekly that 20-year-old Kylie is “at least four months” pregnant, which would also make her due in January 2018.

One Twitter user wrote: “Anyone else think Kylie is just carrying a baby for Kim & Kanye?”

Another added: “If Kylie Jenner is actually pregnant, it’s because she’s Kim’s surrogate. She’s a business woman come on now.”

It was previously reported Kim and Kanye had chosen a San Diego mother in her late 20s as their surrogate.

Both Kylie and Kim have yet to comment on the rumours.
