Amanda Seyfried has given birth to a baby girl, her rep confirmed to People.

The actress wed partner Thomas Sadoski just in time, with the couple marrying in a secret ceremony last week.

The Newsroom star Sadiski announced the news when he appeared on The James Corden Show, revealing they chose to elope in the US countryside with a celebrant.

“We just took off into the country with an officiant, just the two of us, and we did our thing,” Sadoski told Corden, adding his new wife is “the person I love, admire, and respect most in the world.”

Elaborating on the low-key ceremony, he said “It was beautiful. It was everything that it should be. It was just the two of us talking to each other.

“It’s great, it’s kind of perfect. [After the ceremony], you take the dog and you walk through the country and go home. And you like have your life. We went out to dinner, we did great, it was awesome. We had a great day. It was perfect.”

Mean Girls star Seyfried, 31, who announced in November she’s expecting her first child with Sadoski, met her husband-to-be in in Broadway play The Way We Get By last year. They played two people that have a one-night stand.

Amanda and Thomas reconnected again when they both starred in The Last Word, and announced their engagement in September.
