Many still remember a picture that was leaked to the media, which showed the pop star Rihanna, with her beautiful face covered in bruises after a violent argument with her ex-boyfriend Chris Brown.

Now appears in an image a little disturbing, but fortunately fictitious. Rapper Eminem was invited to play with him the success''Love the Way You Lie,''a song that explicitly depicts a relationship in which there is physical abuse.

The debate soon emerge: "The song is a message against domestic violence or an enhancement of it?, Maybe an apology? And besides, how can we explain the role of Rihanna, who has said he expects young people to learn from their experience with Brown?

The only sure thing is the success of the song, which remains at the top of the Billboard Hot 100. Even before the launch of the stunning music video for the song lyrics were enough to get anyone's attention.

''I'm going to stop me and I'll see how I burn,''Rihanna repeated in the chorus with a catchy rhythm. ''But that's okay because I like how it hurts.''

Eminem, who sings the verses of the piece, makes it quite clear what it is. ''If another (injury) is after me,''he says later, "I'll tie her to bed and set fire to the house.''

In the video, Megan Fox plays a girl who is leaving her boyfriend, played by Dominic Monaghan, who promises that what happened does not happen again. But then he admits he is lying:''I apologize but I know they are lies.''

Rihanna, 22, was unavailable for comment about the song, his publicist said in an e-mail.

As for Eminem, his turbulent relationship with his ex-wife Kim Mathers is known by many. His song''Kim spoke of fantasies about killing her.

Eminem has said he went to Rihanna because she was the perfect person to make the song.

But really,''may serve to show something? That depends on the context in which young people hear and see, "said Marjorie Gilberg, executive director of Break the Cycle, a group against violence among adolescents.

''The danger is that pop culture defines our social norms,''said Gilberg. ''We do not want the message of this song is that this type of relationship is acceptable. So this song must be viewed in the context of real information provided by adults, including parents and teachers.''
