Let's stay on the celebrities a minute longer for this, a slow Tuesday morning. Like Scarlett Johansson before him, Eminem announced this week that he's going to be designing a collection of Nike tennis shoes. But, unlike Scarlett, this actually makes more sense, given how predominant a subject sneakers are in hip hop. Plus, he's doing it for a good cause, giving some of the proceeds to charity. Here's some:

The Grammy-winning rapper designed uppers for eight shoes in the series, including the Air Max '87 and the most recent Air Max 360. His reinterpretation of the upper has been laid onto the original blueprints for each of the Air Max shoes to create a unique set of designs.

Eight sets of the footwear -- a total of 64 pairs -- will be produced for the auction. Proceeds will benefit Eminem's Marshall Mathers Foundation, which provides funds for organizations working with troubled youth in southeast Michigan, and ninemillion.org, a global campaign to bring education and sports programs to children in refugee camps across the globe.
