The Hollywood actor and his human rights lawyer wife held hands as they arrived at the New York Film Festival on Tuesday, 29 September, the day after their one-year anniversary.
Amal - who wore a vibrant green dress - didn't walk the red carpet with George, instead keeping a low profile while he celebrated the 15th anniversary of his movie O Brother, Where Art Thou?
He told People: "We had a beautiful anniversary, and we're having fun."
The couple married in Venice on 28 September 2014 at a lavish ceremony held at a hotel overlooking the Grand Canal. Guests in attendance included Matt Damon, Cindy Crawford and her husband Rande Gerber, who is George's best friend.
Cindy said in a recent interview she wouldn't be surprised if George and Amal had children.
"Rande always said he will when he meets the right girl," she said. "If you had asked me five years ago, George was like 'I am never having kids'. George has surprised me so who knows. I would never say never."
