Ruffalo and Sunrise have been married since 2000 and they share three children: Keen, 23, Bella Noche, 19, and Odette Moon, 16.

The Avengers star originally met his wife on the streets of Los Angeles in 1998. He told Men's Journal in 2017 he and a friend met her on the street and that he suspects his friend was initially interested in Sunrise.

"I don't think he wanted us to meet," he said at the time. "But I saw her and was like, I'm going to marry that girl.' "

"All I had was my decency, wit and charm — I didn't have anything," Ruffalo recalled. "When I met her, she was like, 'You don't have a driver's license, you don't have a credit card. What is wrong with you, dude? I can't be with you!' I was living in a converted garage, and she was there for that, she was game. She believed in me."

"She was like, 'I know you're a really good actor,' and I was like, 'You haven't really seen me act yet.' And she was like, 'I just know it, I can tell.' "

They celebrated their 24th wedding anniversary together on June 11. When the Poor Things actor received a star on the Hollywood Walk of Fame in February, he told PEOPLE it was the "most glorious thing" to have his family with him to celebrate, and he added that the honor is "theirs as much as it is mine."

"It's not easy being married to an actor and being the children of an actor. I'm away a lot," he said at the time. "This whole thing is distorting and difficult."
