A few months ago, Catelynn told In Touch magazine that she and Tyler were ready to try for another child. Turns out, she might have already been pregnant when she said that!
The reality star just shared this beautiful baby bump photo with the hashtags "it's official" and "4 months."
Like a lot of women do, she was probably waiting until later in her pregnancy to make the announcement (according to Web MD, more than 80% of miscarriages occur within the first three months of pregnancy).
While we're obviously surprised by the news, it didn't come as a total shock because Catelynn's mom and brother accidentally spilled the beans on Facebook earlier this summer, although she never confirmed or denied their comments.
Now, it's definitely confirmed and we couldn't be more excited for Catelynn and Tyler!
