Sacha Baron Cohen and Isla Fisher have donated $1 million (£670,000) to Syrian refugee children.
The comedian and his actress wife have given the money to two charities - Save the Children where it will provide measles vaccinations and the International Rescue Committee (IRC), where it will fund a range of initiatives.
Syria remains ravaged by a civil war that began in 2011. More than 250,000 are thought to have been killed and millions have been forced from their homes, contributing massively to the current refugee crisis in Europe.
The IRC is run by David Miliband. The former UK foreign secretary said: "Sacha and Isla's donation is a great expression of humanity, and a challenge to do more for the most vulnerable.
"I hope it is an example to many others seeking practical ways of making a difference during the Christmas and new year season."
The Save the Children donation was made through an appeal run by The Times.
Justin Forsyth, CEO of Save the Children, said: "By allowing us to make their generous donation to Syrian children public, Sacha and Isla are helping highlight the tragedy of the issue today.
"These are desperate times for Syrian families facing bombs, bullets and torture in Syria. The couple's donation will save many thousands of lives and protect some of the most vulnerable children."
British Baron Cohen is best known for his characters like Ali G and Borat while Australian Fisher starred in "Home and Away" as well as films such as "The Great Gatsby".
The couple married in 2010.
