Helen Mirren just told a UK magazine that there were parts of her below the waist that she didn't like much. Her solution? The Oscar-winner is stepping onto the Nintendo Wii.

Mirren -- who recently went topless for New York Magazine -- has just been tapped to promote Wii Fit Plus in the company's UK holiday campaign.

Take that, Jane Fonda!

Glad in chic workout wear -- slim drawstring pants and wraparound tops -- the inspirational "gramazon" breaks a sweat as she exercises using the interactive fitness system. Hot dame!

"This year's star line-up is the best yet, demonstrating the wide appeal of Nintendo products," Nintendo UK marketing director Dawn Paine says in the release. "This Christmas, with the help of our celebrity friends, we will be helping the nation play together and have fun whatever their age."
