Joanna Gaines' baby bump is growing day-by-day and here are some new photo-proofs

Although Chip and Joanna Gaines have four children together, this is the first time they have been sharing this much information during pregnancy.

Joanna's current pregnancy is her first in the public eye because, by the time their TV series, Fixer Upper, got big, it had been a few years since she and Chip had their youngest child.

According to Country Living, although fans will have to wait some months to see the baby, Joanna is happiest than ever, as proven by her recent posts.

The reality star recently turned 40, and to celebrate her birthday, she posted a picture of her biggest baby bump to date. 'This is 40. And I like it...' she captioned.

In the picture, she's playfully bitting what seems to be a piece of cake or a cookie, laughing in a tastefully decorated living room.

In one of the posts, Joanna flaunted a short-sleeve maxi maternity black dress, which covered her bump beside a bathroom door from a flip house project the couple is working on.

One of the last projects the couple has been working on is the launch of Joanna's new Waco restaurant, Magnolia Table.

Joanna also posted a picture captioning about the launching of the restaurant and asking fans about them noticing her baby bump.

Last month, the Fixer Upper stars were seen while filming a scene for their show. Although Joanna is wearing a baggy sweatshirt, her stomach is visible.

The interior designer also shared some other baby bump photos, including pictures from the Tim Tebow Foundation Celebrity Golf Classic, possing with Chip and some other personalities.

In the first picture, Joanna posed next to Chip and Tim in a black one-shoulder cocktail dress, but the baby bump isn't as visible as in the last picture of the series.

Soon after the couple revealed the pregnancy news, Joanna posted a sonogram video, claiming that Chip swore he could already tell it was a boy.
