British singer Leona Lewis has taken aim at pop stars such as Rihanna and Miley Cyrus for turning young children on to their raunchy dance routines.

The Bleeding Love hitmaker has called on parents to control which music videos their children are watching on Tv and online, insisting certain stars are setting a bad example by popularising controversial routines.

She tells Britain's Daily Mirror newspaper, "Being sexual and in your face is not great for girls who are quite young. It depends what environment you’re brought up in, but personally I've got a god-daughter and little nieces and I don’t want them to see me acting crazy and naked in my music videos.

"But then when my little god-daughter is watching videos and doing all these moves, I say to my best friend, 'You need to turn that off. She shouldn’t be watching that’. So it’s up to the parents as well to be able to control what their children are watching. It’s like, 'Don’t twerk! You’re a six year old. Stop it'."

Lewis isn't naming names but she thinks all pop stars who bare all in videos and twerk and grind in skimpy attire on Tv are "young and sometimes dumb".

She adds, "They’re just expressing themselves how they want to. Girls are not perfect, we all make mistakes."
