Singer Kelly Clarkson has slammed artists like Hilary Duff and Mandy Moore - because they have released greatest hits albums too soon.
The 25-year-old has enjoyed a string of hit songs since winning TV talent competition American Idol in 2002 - but insists she won't be putting out a compilation of her best tracks until later in her career.
She says: "Doing a greatest hits would be crazy. I am not 50. Artists who do one after three albums think their career is coming to an end."
