Nelly Furtado has blasted Madonna over her reluctance to age naturally.

The 30-year-old "Maneater" singer insists she won't try to make herself appear younger in order to boost her career and would rather enjoy tea and biscuits than undertake a gruelling exercise regime.

She said: "I am not ready to adjust physically, just to be marketable. My sell-by date will run out eventually.

"Unlike Madonna, I wouldn't be willing to do Pilates round the clock, just to slow down the deterioration of my body. I prefer to sit in the kitchen, drink tea and eat biscuits."

Furtado - who is married to sound engineer Demacio Castellon and has a 6-year-old daughter, Nevis, from a previous relationship - took a two-year break after she finished promoting her 2006 album "Loose" and says she was enjoyed having the time to lead a more normal life.

She explained to Germany's Petra magazine: "After the tour I was terribly exhausted and had to find a way back to a healthy routine. I cooked chicken soup for my family and just enjoyed everyday life. The small things that make you happy are important to me."
