Double congrats! Jennifer Carpenter is pregnant and engaged to boyfriend Seth Avett, her rep confirms to Us Weekly.

The Dexter alum stepped out in Los Angeles over the weekend with her baby bump on full display in a fitted three-quarter length tee.

Carpenter, who was previously married to her former Dexter costar Michael C. Hall from 2008 to 2011, first started dating the Avett Brothers musician in June 2013, after years of being just friends.

"Jennifer met Seth about four years ago at a concert," an insider told Us after Us Weekly revealed the duo had turned romantic. "She loves music and has always been a big supporter of the band. The relationship developed over the past few months."

“They have a lot in common and seem to have a similar sense of humor,” the source added. “There is an ease about their relationship. They are a good match."

This will be the first child for the couple. Avett was previously married to Susan Avett, whom he divorced in 2013.
