Hugh Jackman yet again proved he's one of the nicest guys in Hollywood, singing his mother-in-law's praises as she was honored at Monday night's star-studded Angel Ball in New York City -- a fundraising event for Gabrielle's Angel Foundation, which honors individuals who have made significant humanitarian and philanthropic contributions in support of cancer research.
Jackson's mother-in-law Fay Duncan was recognized for her work as chairman of the Fight Cancer Foundation.
"It means everything to me. It's a fantastic ball," Jackman told ET about supporting his mother-in-law. "What [Denise Rich, the Grammy-nominated songwriter and philanthropist who started Gabrielle's Angel Foundation] has created is amazing, and her foresight to honor this incredible woman -- my mother-in-law -- and I'm not just saying that to get brownie points, she really is incredible. She started the Fight Cancer Foundation in Australia with her colleagues. ... It's amazing what they've done."
Jackman also commented on reports that he'll be starring in director Bill Condon's big-screen adaptation of the musical The Greatest Showman on Earth, playing PT Barnum himself.
"It's true that I want to do it. It's true that there is a project not fully green-lit yet," he said. " ... But I really hope so. It's got a lot of great momentum. Fingers crossed."
The Angel Ball, which featured performances by Usher and Pharrell, raised three million dollars for cancer research.
