George Clooney is Proud of Amal for "Albie Awards", Honouring Defenders of Justice.

People.com: George Clooney is one proud husband!

The Oscar-winning actor, 61, was joined by his wife, Amal Clooney, 44, at the inaugural Albie Awards, hosted by their Clooney Foundation for Justice on Thursday night in New York.

Outside of the New York Public Library, George told PEOPLE what he loved most about working with Amal to create the event.

"Well we collaborate on everything. We collaborated on twins!" the Ticket to Paradise actor said. "But you know, this is an exciting one because Amal's gotten journalists out of Egypt, out of Azerbaijan, prisons, out of — all over the world, Myanmar."

The Albie Awards honored those who devote their lives to justice. It was attended by celebrity guests including Meryl Streep, Dua Lipa, John Oliver, Julia Roberts, and Bruce Springsteen and Patti Scialfa, among others.

George said that their work on the Albie Awards and with their foundation is something that his wife "happens to be really especially gifted at."

He added, "My father's a journalist. I have a great affinity for them — her mother's a journalist. So it's really exciting for me when she's able to get people who are wrongly accused for doing their job out [of prison]. So, for me, it's just — I couldn't be more proud of my wife."

As for what George hopes the pair will teach their 5-year-old twins Alexander and Ella, he said, "There's tons of stuff. But the number one thing is: challenge people with power and defend people without power."

Named after Justice Albie Sachs, George and Amal created the Albie Awards to shine a spotlight on defenders of justice who are at risk for what they do.

Albie received a lifetime achievement award Thursday for his heroic commitment to ending apartheid in South Africa.
