Leave it to Shaquille O'Neal to go where Arnold Schwarzenegger fears to tread. The L.A. Lakers' MVP of the NBA Finals, who seems to be everywhere these days, has become the latest celebrity shareholder in the financially troubled Planet Hollywood restaurant chain. (Earlier this year Arnold sold off his stake, and other celebrity investors, including Bruce Willis, Sly Stallone and Demi Moore, also left the company.) Planet Hollywood announced on Tuesday that Shaq will make personal appearances at the eateries and on the menus, which will begin offering "The Shaq Shake." "I plan to do for Planet Hollywood as I have done for the Lakers," he said in a statement.
