Amanda Seyfried, 31, and Thomas Sadoski, 40, welcomed their first baby, a girl, EOnline reports.
Amanda's rep confirmed the birth late Friday, after E! first reported Seyfried was pregnant, back in November.
At the premiere of the couple's other big first — their first joint movie project, "The Last Word" — earlier in March, Seyfried told E! of her impending motherhood, "I'm ready to go. I'm ready to meet the kid!" Sadoski confessed he was "terrified, but I couldn't be more excited."
Last week, Sadoski announced on "The Late Late Show with James Corden" that he had secretly married Seyfried on March 12, saying "We just took off into the country with an officiant and just the two of us, we did our thing." Sadoski deemed the intimate ceremony "perfect" and "everything that it should be."
The two have known each other since working on the Neil LaBute play "The Way We Get By" in 2015, which was, ironically, about a one-night stand.
There is no word yet on their daughter's name, but "Fetch" has a nice ring to it.
