France's first lady, Carla Bruni-Sarkozy, will sing in New York on Saturday to celebrate South African icon, Nelson Mandela's 91st birthday.

The performance will mark her first public appearance since marrying French president, Nicolas Sarkozy.

The French president will attend the event, where his wife will perform along with Aretha Franklin, Queen Latifah, Stevie Wonder, Cyndi Lauper and others, organizers said Friday, Reuters reported.

Bruni-Sarkozy, 41, released her third album months after in February 2008 following her marriage to Sarkozy. The French first lady will perform with former Eurythmics musician Dave Stewart.

More than 18 months ago, Stewart and Bruni-Sarkozy began writing songs that have yet to be released. Stewart, 56, said in an interview with Reuters that he wrote the melodies, while she wrote the French lyrics, Reuters reported.

Bruni and Stewart will perform her biggest hit Quelqu'un m'a dit (Someone told me) and a version of Bob Dylan's Blowin' in the Wind.

The Mandela Day concert will take place at New York's Radio City Music Hall at Madison Square Garden and will feature South African Soweto Gospel Choir and Senegalese singer Baaba Maal.
