No one said much when her Facebook, Twitter and Instagram accounts pushed out altered visages of Jesus, Marilyn Monroe, the Grinch, Homer Simpson and the like.

Social media lit up, many questioning her use of the civil rights icons to promote her album.

Madonna responds to leak, releases songs as Christmas gift

Madonna’s new album isn’t expected to be out in its entirety until spring, but six tracks were released last month ahead of schedule after unfinished versions of her newest songs found their way onto the Internet.

Leaks have tormented Madonna in the past. In 2003, the singer’s website was defaced, and last month, every song off her “American Life” album was leaked online.
