50 Cent: 'Rap lyrics reflect harsh realities of life'

50 Cent is refusing to give in to critics calling for rappers to clean up their lyrics, insisting expletives used in the music are simply reflective of the "harsh realities" of life.

Hip-hop stars have come under attack for their regular use of words like 'ho' and 'bitch', particularly after the Don Imus controversy last month, where the American DJ referred to a female basketball team as "nappy-headed hos".
