Kardashian fans are speculating whether Kylie Jenner is in fact the mystery surrogate that carried Kim Kardashian-West and Kanye West's new baby.
The rumours have been circulating online since Kim and Kanye announced the arrival of their third child last night.
After reports emerged last week that Kylie was in labour with her own child, some fans on Twitter reckon she was in fact carrying her half-sister Kim's baby all along.
But there's been no confirmation at all from the Kardashian-Jenner family about Kylie's rumoured pregnancy.
Kim announced the news of their baby's arrival on her website and later tweeted the same message:
The mother of three is clearly excited about the arrival of the latest addition whose name hasn't been released yet:
