Amanda Seyfried and husband Thomas Sadoski have announced the birth of their second child.

The couple, who are already parents to three-year-old daughter Nina, shared the happy news by teaming up with two charities, the International Network for Aid, Relief and Assistance (INARA) and War Child.

“Since the birth of our daughter 3 years ago our commitment to the innocent children that are so brutally affected by conflict and war has been a driving force in our lives,” they said in a statement shared by both organisations on social media.

“With the birth of our son the work of INARA and War Child has become our North Star.”

INARA added: “We are so happy to join with @warchildusa to be the first to announce that our board members @mingey and @thomas_sadoski welcomed their second child into this world.”

Both organisations work to protect children caught up in conflict.

Seyfried, 34, and Sadoski, 44, also shared the statement on their personal Instagram accounts alongside a sweet photo of their son sleeping.

The Mamma Mia star added: “@thomas_sadoski and I made a little man.”

The couple had not previously revealed the news that they were expecting a baby.

Seyfried and Sadoski married in 2017 and welcomed their daughter shortly after.

They are the latest stars to choose to reveal baby news in partnership with a charity, after Orlando Bloom and Katy Perry announced the arrival of their first child together, a daughter named Daisy, in a statement shared by Unicef.
