The `Wannabe` hitmaker - who has six-year-old daughter Bluebell Madonna - has cut out sugar from her diet and says laying off the booze makes her look and feel healthier. Geri told HELLO! magazine: "Alcohol is full of sugar. Besides, if I`m going to find the balance of being a mum and having a social life, I just can`t put a hangover in there." She added: "I can`t restrict myself, but I do try to abstain from sugar. That`s my thing - if I have one little bit, it`s a trigger. "I`m addicted to it. And sugar is ageing. Without it my skin is better." The former Spice Girl, 40, has been scrutinized over her yo-yo weight and changing appearance in the past, but is adamant she would never resort to plastic surgery and plans to grow old gracefully. Geri explained: "A lot of women lie about their age. But if I`m to be true to what I`ve stood for all this time, then it`s important to say this is my age and it`s fine. "I don`t think there`s anything wrong with going down that route, but each to their own. "I would say easy does it, as my mother says, we don`t know the long-term side effects - so the jury`s out."
