E! News were first to report that the Pretty Little Liars actress is pregnant earlier this month.
Now, Troian has been spotted out in public, showing off her growing belly for the first time.
How cute does she look?!
Troian married Suits star Patrick J. Adams in December 2016 after three years of dating, and this will be their first child together.
While the couple have stayed pretty quiet about the news, her Pretty Little Liars co-star Lucy Hale has gushed about it.
“I think we’ve all known for a bit,” Lucy told Us Weekly last week. “I’m really happy for her.”
We can't wait!
