The 35-year-old is expecting her second child with husband Brian Hallisay.
"Jennifer and Brian are thrilled to be expecting their second child later this year," her rep confirmed in a statement to E! News.
The couple, who secretly wed in 2013, are already parents to daughter Autumn, who they welcomed in November that year.
The "Criminal Minds" star and Hallisay began dating after co-staring on Lifetime's now cancelled series, "The Client List".
The brunette beauty has previously talked about how super smooth her first pregnancy was, hopefully this time will be just as great!
"I feel very lucky," she told Us Magazine while pregnant with Autumn. "Some women have really rough pregnancies. I've not had one. It's been really nice and we have been enjoying it so we feel really lucky."
Congratulations to the happy parents!
