Khloe however has now confirmed the announcement will unfold on the family's reality show, with the star replying to a fan on Twitter.

While it's possible Thompson dumped his pregnant girlfriend to date a celebrity, it's unclear how the athlete and Craig ended their relationship-and she hasn't commented on Thompson dating Kardashian, or made a statement about them expecting a baby.
Kardashian is also very happy with her and Thompson's "healthy" relationship. Love you bunches and we are all sending you a gazillion positive vibes!
To her fans, Kardashian explained that they took their time revealing her pregnancy as they wanted to enjoy it privately as much as they could, sharing it first only with close family and friends.
The 33-year-old reality star said motherhood is her "greatest dream realized".
She received more than one million likes in the first 15 minutes of the post being uploaded to her account.
The news has fans hoping that Kardashian's youngest sister, Kylie Jenner, will use the show to let the cat out the bag, too.
