Algerian Malika, who is recovering from an illness, claimed Zidane, 34, was simply protecting her honour when he butted Materazzi in Sunday's final.
She told friends: "I am utterly disgusted by what I have heard. I praise my son for defending his family's honour.
"No one should be subjected to such foul insults on or off the football pitch and I don't care if it was a World Cup Final.
"I have nothing but contempt for Materazzi and, if what he said is true, then I want his balls on a platter.
Maman Zidane est pas contente.
