Joanna Gaines shows off her baby bump as she celebrates her 40th birthday

Having a child is one of the most special moments in a person's life. With four children already, Chip and Joanna Gaines know that very well.

The famous television stars have built more than houses in the past eleven years - they have built a family. Recently, on April 19, 2018, Joanna shared a photo revealing her baby bump.

The couple is expecting their fifth child, and they couldn't be more excited to welcome the baby into the family now that they are in a new phase of their lives, as reported by Pop Culture.

The photo, which was posted on Joanna's Instagram page, didn't just show how much her belly has grown in the past weeks; it also served to celebrate the fact that the former Fixer Upper turned forty.

Joanna appears in the photo wearing a gray sweater and dark leggings, holding a mug and snacking on a donut that she took from the pile stacked on the table, right next to a vase of flowers.

According to the source, while most women tend to dread the big leap that is becoming forty years old, Joanna has proudly embraced it and admitted that she was more than comfortable with her age.

Joanna and Chip are already parents to Drake, 12, Ella, 11, Duke 9, and Emmie, 7. The gender of their fifth children was revealed to be a boy, and the announcement was made by Chip, with the help of a brand new friend.

"It’s a little boy and I need a ‘D’ name and so far, all I could come up with was Dragon, and she’s like, ’You are not calling that baby Dragon!’ Can you help me?”
