Kanye West is to attend anger management classes to help him cope with his mood swings, according to reports. The rap icon is said to have alarmed members of his management team following a series of outbursts in recent months. He reacted furiously to being booed at the Bonnaroo Festival in America last month, launching a tirade via the blog on his official website. A UK tabloid claims he is to seek professional help to address the situation. A 'source' explained: "Kanye's management team came up with the idea. "His mood swings were beginning to play a part in his commercial enterprises as people felt he was miserable all the time."
