50 Cent has hit back at R+B singer Alicia Keys for criticising gangsta rap - insisting her comments were "not really bright".
Keys courted controversy by voicing her opinions on the hip-hop subgenre, telling U.S. magazine Blender, "Gangsta rap was a ploy to convince black people to kill each other."
And her comments have enraged rapper 50 Cent - real name Curtis Jackson - whose music is said to fall into the gangsta rap category.
He tells TMZ.com, "I don't like people who don't like me ... that statement changes my perception of Alicia Keys totally. It's just not really a bright comment ..."
Keys has since retracted the statement, insisting her words were taken out of context.
