REVELATIONS

La Toya Tells All: La Toya Jackson told “Today’s” audience on Thursday that her father physically abused many of her siblings, including superstars-to-be Michael and Janet, when they were children. Joe Jackson “would beat everybody in the family,” La Toya said on the show, where she was plugging her new biography. She’ll also be hawking the book in and on November’s Playboy magazine. She posed for the cover and a nude pictorial inside, where the magazine is excerpting the book. La Toya says mother Katherine is “bitterly upset” over the nude pictorial, La Toya’s second for Playboy.
