Blake Shelton is spending time protecting his precious assets while on the road this week. No, not his sexy singing voice but his Guitar Hero-playing fingers. Shelton is the newest country star teaming up with Xbox 360's 'Game with Fame' program. He is challenging fans to a live game of 'Guitar Hero World Tour' this Friday, February 20.

"You better be ready for this," Shelton jokes in a new YouTube video. "I know there are a lot of punks out there that think they can take me on. I'm not sure you got what it takes."

Shelton is taking his gaming seriously. He has been working out his fingers, icing his hands and is ready to do what it takes to kick butt.

You have to be an Xbox LIVE Gold member to take on Blake. If you are, send a friend request to the Gamertag 'Blake GWF' and be online by 1:30 PM ET on Friday.
