Madonna has revealed that her adopted son David Banda is one of her biggest fans.

While talking about four-year-old David, one of two children the pop star adopted from Malawi, the star, 51, told GMTV, “He knows every song, every word, every step, and he wants to wear all the costumes. He likes my dress that I wear in La Isla (Bonita).” Meanwhile, Madonna, who has two biological children - Lourdes and Rocco - and has adopted David and Mercy, hasn’t ruled out expanding her family further by adopting another kid, reports The Telegraph.

Asked if she would adopt again, she said, “Never say never.”

“I have four children now and I would like to think I am a good mother. I feel a great sense of satisfaction in all areas of my life,” she added.
