50 Cent has criticised US chat show host Oprah Winfrey yet again.

The outspoken rapper has claimed that Winfrey no longer reflects the views of black people because she is so desperate to appeal to white audiences.

"Oprah started out with black women's views but has been catering to middle-aged white American women for so long that she's become one herself," he explained in an interview with Elle magazine.

Fifty, real name Curtis Jackson, previously complained about Oprah's refusal to invite rappers on to her show. However Oprah has insisted that her stance is based on the "hateful and degrading" lyrics of certain rap artists.
