The world might ogle over Hugh Jackman's super-fit physique, but his biggest fan of all doesn't like it when he's too muscular!

"[My wife Deborra-Lee Furness is] always upset with me if I'm in really good shape," the 42-year-old X-Men star told Australia's "She's like, 'I think you're forgetting the contract of marriage -- ultimately everything is about me looking better, so enough with the training."

Jackman said Furness, 55, prefers him rough instead of buff. "Let me give you a little insight into my wife," he said. "I met her on a prison drama where I had tats all over my body and a mullet, and that turned her on. She likes the bad boys."

"Overall, Deb would say to me my job is to be out of shape so that she can look as good as possible," Jackman added. The duo have been married for 15 years and have two children together: Ava, 6, and Oscar, 11.

But the Real Steel star admitted to the October issue of Men's Fitness that he mainly works out because it's part of his job. "I don't really enjoy training. People say it's addictive, but I'm like, 'Not so much,'" he explained. "If I weren't getting paid or didn't have a character like Wolverine to maintain, I would just be a tall, lean, fit guy."
