U.S. first lady Michelle Obama met with French first lady Carla Bruni-Sarkozy for the first time on April 3 and agreed to work together to draw attention to the global HIV/AIDS epidemic, Agence France-Presse reports. The two met for a one-on-one lunch while their husbands, U.S. President Barack Obama and French President Nicolas Sarkozy, had talks before the NATO alliance’s 60th anniversary summit in Strasbourg, France.

According to the article, the women will talk via telephone in the coming weeks to develop a joint plan to address HIV and other health concerns.

Bruni-Sarkozy, a former model and singer-songwriter, was spurred into advocacy after losing a brother to AIDS. Last December, she was named a goodwill ambassador for the Global Fund to Fight AIDS, Tuberculosis and Malaria; in February, she made her first trip on behalf of the organization to Burkina Faso, West Africa.
