Once her mental fitness regimen is complete, Kidman’s brain age will be revealed to the public, video-game Web site 1up.com reported.

"I love the concept that Nintendo is reaching out to new audiences with their self-improvement products,” Kidman said in a press release. “Most importantly, I've quickly found that training my brain is a great way to keep my mind feeling young."

Kidman was chosen as the video game series’ representative because of her widespread appeal to mainstream audiences of all ages and backgrounds, Nintendo said.

"The Brain Training phenomenon is sweeping the globe, enjoyed by over 10 million people from grandparents to Oscar-winning actors," Dawn Paine, marking director of Nintendo UK, said in a statement. "We believe that Nicole Kidman's leading role in the campaign and the revelation of her DS Brain Age will surprise and excite people all over Europe."

The video-game software, geared to those aged 9 to 99, is set to hit Europe on June 29 and the United States on August 20.

Kidman has also appeared in advertisements for Chanel perfume.
