In an interview appearing in the magazine's December issue with a 20-page photo shoot reminiscent of Bruni-Sarkozy's time as a top model in the 1990s, she admitted she disagreed with her husband on the question of gay marriage and adoption.
"I am rather in favour of gay marriage and adoption, I have a lot of friends — women and men — who are in this situation and I see nothing unstable or perverse in families with homosexual parents," she said.
French President Francois Hollande, who defeated Sarkozy in a May presidential election, is pushing plans to legalise same-sex marriage and adoption despite fierce opposition from Catholics and rightwing groups, including most of Sarkozy's UMP party.
Bruni-Sarkozy refused to answer questions about her husband's future political career, saying only: "It was a beautiful adventure, but today I just want to go back to being a citizen like any other."
Bruni-Sarkozy, a model and singer whose fourth album will be released next spring, married the divorced Sarkozy in 2008.
