The two singers are joining Beyonce and Solange's mum Tina Knowles-Lawson for the Love on Louisiana: An Essence Hometown Heroes Tribute initiative.

The event, which will take place at Raising Cane's River Center on 20 November (16), will double as a dinner and an awards ceremony honouring students and teachers who have helped rebuild areas of Baton Rouge.

"Louisiana is a special place in my family's history, and we are committed as a family to never forget the city and the people of Baton Rouge," Tina, who will co-host with Solange and Kelly, said in a statement. "It breaks my heart to see the unimaginable disaster and destruction caused by the flooding and we will stand and support every effort in place to help the people most affected."

All proceeds from the evening will benefit Habitat For Humanity.

Tina's eldest daughter Beyonce will also support the cause through her BeyGood foundation.

In August (16) historic floods ravaged areas of Baton Rouge, destroying more than 60,000 homes and causing $8.7 billion in damages.
