“We're so excited that it's finally happening. Thank you for all your love and well wishes. I look forward to all the belly touching! Xx”

The beauty has been very open about her struggles to get pregnant in the past.

During an episode of the Fab Life Show, Chrissy, who hosts the show with Tyra Banks, explained how difficult she found it everytime someone asked her when she was gong to have kids.

Watch her speak about the issue here:

In the interview she says: “Every single time I sit down for an interview with anybody.

“I can’t imagine being that nosy to be like, ‘So, when are the kids coming?

“Because who knows what somebody’s going through?… I will say, honestly, John and I were having trouble…it’s been a process.

"We’ve seen fertility doctors, and then once you open up about all those things to other people you start learning that a lot of other people in your life are seeing these people, and they have this shame about it.”
