Earlier this week , Prince ,paris and blanket presented a ckeck for $10K to the L.A. Housing Corporation ...a group that provides shelter for homeless families . Sources say Michael used to take his kids to volunteer with the group .
Sources said the massive chunk o'change came from grandma Katherin e Jackson's memorabilla biz .
MJ heirs made the donation on behalf of his Heal the World Foundation . All three of them joined the group's Youth Board of Advisors last year.
