Toby Keith has landed the cover of Forbes magazine's special issue on the 100 highest-earning celebrities. The country star has quietly built himself a business empire and is now thought to be worth around $500 million. He pocketed $65 million last year alone. In addition to his own records and concerts, Toby owns a chain of I Love This Bar & Grill restaurants, a line of Wild Shot mezcal tequilas and has a multi-million-dollar endorsement deal with Ford. He even gets a piece of Taylor Swift's action through his Snow Dog label partnership with her Big Machine record label.
