Sarah Harding claims Britney Spears has "lost it".
The Girls Aloud star says the 'Toxic' singer - who recently lost custody of her two children following her increasingly erratic and wild behaviour - became famous far too young and hasn't had the right people around her to help her deal with the pressures of the celebrity world.
She said: "I don't mean this in a horrible way but I feel like Britney has lost it a bit. I feel sorry for her. I just feel she doesn't have the right people around her. She's got issues. She's had too much too young."
The 25-year-old blonde insists there is no way she will end up like Britney, who has been to rehab, because she was able to live a 'normal' life before finding fame in the hugely popular girl group.
Sarah - who joined the band when she was 20 - added in an interview with New! magazine: "I won't end up like her! I managed to live my life before I got in the band and I still live my life. I'm lucky."
Sarah also criticised Victoria Beckham's fashion sense, branding it
over-the-top.
The 'Call The Shots' singer thinks the Spice Girl should tone down her style but realises Victoria has built a successful public image with her high fashion look.
Sarah said: "I think Victoria's style is a bit too much sometimes. I think it's nice to be a bit more casual. But at the end of the day, it's what she's known for."
