Kim Kardashian West is reportedly expecting twins.
The 'Keeping Up With The Kardashians' star - who announced she was pregnant with husband Kanye West's baby yesterday (01.06.15) is believed to have had two eggs fertilised.
A source shared: "Kim has told a handful of people that she had in vitro and that two eggs were fertilized. She is waiting to see if they both 'stick' before she makes any kind of announcement.
"She has to wait and see if they are both OK. And she is waiting to get an OK from her doctor that both the fertilized eggs are healthy."
The 34-year-old television personality - who has 23-month-old daughter North with the 'Bound 2' rapper - is also said to be keeping a low profile about her happy news - with only her mother, sisters and husband knowing about the twins - so she does not upstage her stepmother Caitlyn Jenner, who was previously known as Bruce Jenner before undergoing a gender transition, who revealed her new name and the first photographs yesterday (01.06.15).
Meanwhile, the family are said to be planning an outing together with Caitlyn so they can show their support for the 65-year-old former Olympian.
Another insider added to NYDailyNews.com: "They're planning a family outing that's going to be 'accidentally' filmed by the paparazzi. It's going to be Kim, Kanye and maybe others, going out with Caitlyn to show their support.
"They're talking about doing it in New York and not L.A. Kris is reluctant to take part in it. It would happen sooner than later."
