Newlyweds Amanda Seyfried and Thomas Sadoski have welcomed their first child. A rep for the "John Wick" actor has confirmed that the "Mean Girls" actress just gave birth to a baby girl. However, the name of their child is yet to be announced.

The couple began dating after filming "The Last World" in early 2016. That year in September, the two announced their engagement. Two months later, Amanda revealed that she was pregnant by debuting her baby bump while attending a Givenchy event.

During his appearance on "The Late Late Show with James Corden", Thomas announced that he and Amanda tied the knot in a secret ceremony on March 12. "We eloped," he said. "We just took off into the country with an officiant and just the two of us, and we did our thing...We had a great day. It was perfect."

"She's the person I love, admire, respect most in the world," Thomas told James Corden. "It was beautiful. It was everything that it should be. It was just the two of us talking to each other," he said of the ceremony, during which they recited their vows in front of Amanda's dog Finn.

During the premiere of their new film, the pair talked about welcoming their first child. Amanda confessed, "I'm ready. I'm ready to meet the kid." Meanwhile, Thomas said, "I'm blown away by her every day. She does look about ready to pop. It's a pretty amazing thing. I just get to sort of hang back and watch it all happen. That's the great joy for me, trying to learn as much as I can, try to stay out of the way and not screw anything up too much."
