Former Spice Girls singer Mel C, a.k.a. Melanie Chisholm, is critical of Rihanna for being too sexual in her videos and on stage for her young fans.
Mel, who has a two-year-old daughter Scarlet with boyfriend Thomas Starr, has grown concerned about the musician's "inappropriate" imagery.
In an interview with the Daily Mirror (UK), she said:
"People have to take responsibility because we've got to a point where sexualization of children has gone too far. I think music is a big part of that. Women in music are extremely sexual and have young fans. It is inappropriate."
"Rihanna has a responsibility and although culture's always changing, it's changed too much. It needs to be dealt with. It's reached saturation point."
"We owe it to our kids to protect them."
Mel believes RiRi makes many of her X-rated artistic decisions - whipping reporters, dressing in next to nothing, her "S&M" video in general - because she isn't a mother herself. That's something she hopes will change one day.
