Congrats to actress Amanda Seyfried and her brand spanking new husband Thomas Sadoski on the birth of their first child together.

A rep for the couple told PEOPLE magazine that they had a baby girl, but no news yet had been released about her name. The birth comes a week after Sadoski told The Late Late Show that they got hitched in a secret ceremony this month on March 12.

They announced that they were expecting last November 2016. He currently stars in CBS’s  Life in Pieces and she is best known for her role in Mean Girls.

Congrats!
