Proud mum Madonna shares photo of son David in traditional Malawian dress

Proud Mum Madonna has been sharing photos of her son, David Banda, dressed in traditional Malawian dress.

The 11-year-old, who was adopted by the singer from his native Malawi in 2006, was photographed next to a photo of his biological parents in front of a framed map of the world.

The pop star added the caption: "Be proud of who you are and where you come from."

It's the latest posting from the snap-happy singer who has been regularly sharing photos and videos of her twins on social media as they adjust to their new life in New York.

Madonna has six children, four of whom she adopted from Malawi, including Mercy James, 11, who she welcomed into her family with then-husband Guy Ritchie in 2009.

In February this year she announced that she had adopted four-year-old twins Esther and Stella Mwale.

The Like a Prayer singer announced the happy news that she was to welcome the twins to her family, sharing a picture on Instagram of herself walking hand-in-hand with her adopted daughters.

In a statement, she said she was grateful to those who made the process possible.

"I can officially confirm I have completed the process of adopting twin sisters from Malawi and am overjoyed that they are now part of our family," she said.

The singer also has a biological daughter, Lourdes Maria Ciccone Leon, now 20, with her then-trainer and boyfriend Carlos Leon, and a son, Rocco Ritchie, 16, with ex-husband Ritchie.
