PARIS, FRANCE (AFP) - France's first lady, singing ex-supermodel Carla Bruni-Sarkozy, has agreed to star in US auteur Woody Allen's next movie, she told a television interviewer.

"He suggested I appear in his next film. I don't know what the role would be, but I said yes," the 41-year-old Italian-born singer-songwriter told the main evening entertainment show on the Canal+ network.

"I go into everything blindly, or I'd never do anything at all," she added, apparently referring to her showbiz career rather than to her sudden marriage last year to President Nicolas Sarkozy.

"I'm not an actress at all. Perhaps I'll be completely hopeless but I can't miss an opportunity like this one. When I'm a grandmother I'd like to be able to say I made a film with Woody Allen," she gushed. "Woody Allen kindly asked me not to do a film with anyone else before him.

If anything concrete ever comes of it, it'll be a great experience for me." New York filmmaker Allen visited the French first couple in June this year during a trip to Paris to promote his last movie "Whatever Works".

Asked whom he would like to cast in his next film, he said: "Without question, Carla Bruni! I'm sure she would be wonderful. She has charisma, and she performs, so she's not a stranger to an audience."
