The 44-year-old worked hard to get into shape for director James Mangold's 'The Wolverine'.
"He looks like he's photoshopped in the flesh. I say,'It's ridiculous. You look photoshopped'," a website quoted Furness as saying.
"No one is more disciplined, though, he works really hard at it and it is no fun for the family...we can never go out to eat. It's like he's always having another cow or a chicken or broccoli," she added.
Jackman recently said that Furness, who he has been married to for 17 years, isn't a fan of his toned physique and would prefer him to be fat.
"She doesn't approve. I get a hard time for it. Deb tells me, 'Your job, as my husband, is to be fat and chubby, so that I look great'," Jackman had said.
He also insisted that the key to their happy marriage is knowing they have committed to the "right person" and a willingness to make sacrifices.
"Eight percent of a marriage is choosing the right person and with Deb I just knew. Obviously there has to be a great attraction and love. In any marriage, there must be some sacrifices. No marriage survives if both people are selfish," Jackman had added.
