Jo-Ann Strauss and her husband are expecting their third child together

The former Miss South Africa announced the exciting news on Instagram.

“Excited to say that we are expanding our family in 2018. Hence my social media inactivity for the past few weeks,” she wrote.

The beauty-queen-turned-businesswoman added that she has had a tough time with morning sickness.

“Been down with debilitating morning sickness 24 hours a day. Hopefully it’ll get better soon, but grateful for the blessing of having another little angel.”

While Jo-Ann has not revealed when her baby is due, she has already started showing

“Third pregnancy means the bump debuts a lot earlier than with the first… also didn’t think through the idea of a high-waisted skirt…,” she captioned a picture of an outfit she wore to MC the BMW SA Open.

Jo-Ann is already mom of a son and daughter.

She has not revealed her children’s names or their identity.

The 36-year-old is notoriously private when it comes to her family life, and in 2016 explained why she doesn’t post pictures of her children’s faces

Jo-Ann says social media has become a negative place, and she does not want to expose her children to that.

“Yes, I enjoy social media and I guiltily enjoy counting my likes and reading comments, and I’m grown-up enough to know that you can’t please everyone. I just think that social media and the relative anonymity of a ‘username’ has eroded some of people’s manners. I can handle harsh words from strangers for no particular reason, but don’t want to expose my children to that,” she wrote on her Modern Mommy blog.

Despite her tough stance, Jo-Ann still manages to give her followers a sneak peek of her life as a mom.

Congratulations, Jo-Ann!
