Ludacris and Tommy Lee?

That's right. The two have teamed up with the Discovery Channel's new network, Planet Green, to create a show that focuses on green issues. It's called Battleground Earth, and it will feature Tommy and Luda traveling across the country and competing green challenges. They have to try to out-do each other by doing well in the competitions and keeping their entire entourage - tour bus and all - as green as possible. They'll synch up at the end for a concert in LA's Greek Theater to benefit Griffith Park, which was recently torn up by wildfires. That's what we call using your celebrity for good!
