Ms Bruni and President Sarkozy have been married for one year
France's first lady Carla Bruni says she wants to have more children, adding that she will adopt if she cannot have a baby with President Nicolas Sarkozy.
"I'd love to have a child, but I'm not going to fight against nature," the 41-year-old model-turned-singer told the French weekly, Madame Figaro.
"If it is not possible biologically, I'll adopt one," she told the magazine.
The interview, to be published Saturday, comes one year into her marriage to President Sarkozy.
"I'm not obsessed by blood ties... I think you can build a powerful bond without that," she told Le Figaro, explaining her attitude to adoption.
"We can't say that we need children," said Ms Bruni, who has a seven-year-old son from a previous relationship, while Mr Sarkozy has three boys from two earlier marriages.
The interview was carried out during Ms Bruni's trip to West Africa last week to promote Aids projects.
She has also announced plans to create a foundation aimed at developing education, reading and culture among youth.
