But can France's first lady, top model turned songstress Carla Bruni, who married President Nicolas Sarkozy in February, keep spinning the magic once her new album comes out Friday?

Its success, or failure, could be an affair of state.

The Italian-born Bruni (officially Bruni-Sarkozy) makes an unlikely spouse for any national leader. But in France, where a deep conservatism runs through the lush heartland, she is in many ways the very antithesis of a first lady.

A self-described modern woman, the 40-year-old one-time single mother makes no secret of her freewheeling past, including high-profile trysts with the likes of Mick Jagger and Eric Clapton.

Yet while the French have been scandalized by Sarkozy's splashy lifestyle and his very public divorce just months after winning office, they have taken to Bruni in a big way.

With her high-society upbringing and easy elegance, Bruni has gained accolades from the media and favorable ratings in opinion polls.

The title of the new album -- her third -- is revealing: Comme si de rien n'etait (As If Nothing Had Happened). It will be released in many European countries Friday, sandwiched between the G-8 summit in Japan and a Sunday summit of world leaders in Paris. The album comes out in the United States in August, under its French title.

At the Elysee presidential palace -- where the first lady maintains an office but has yet to take up permanent residence -- Bruni's fortunes are of keen strategic interest. An aide and friend of Sarkozy, Pierre Charon, has been assigned to guide her through the minefields of French politics.

"For the moment, she's a good card," said Colombe Pringle, executive editor of the celebrity magazine Point de Vue, before adding: "It can turn very fast. ... It might backlash."

"It's important that [the album] is good," she said.

Sarkozy took office in May 2007 with sky-high approval ratings, but within six months he had used up that reservoir of support. His messy October divorce from Cecilia Sarkozy and a brash, showy style that won him the nickname "President Bling-Bling" alarmed the French.

Beyond image, Sarkozy's failure to quickly bring about promised change, such as easing pinched pocketbooks, sealed the disappointment.

Then came Carla to the rescue. She has brought a measure of calm to the frenetic president and class to the presidential image -- apparently without compromising her essential self.

Despite the boost, Sarkozy's approval ratings remain dismal at around 40 percent -- compared to nearly 70 percent for Bruni in June.

Bruni made her name as a guitar-strumming singer in 2002 with her hit first album, Quelqu'un m'a dit (Someone Told Me).
