They are show business royalty, heirs of the King of Pop. Someday, they will be very rich. But a year after their father Michael Jackson's death, Prince, Paris and Blanket Jackson are normal kids full of fun and pranks, devoted to each other and to their grandmother who is their guardian, according to a lawyer who sees them frequently. They talk about their father and his presence is everywhere in the ranch-style house in the San Fernando Valley where they live. Pictures and memorabilia adorn the walls. “The children are seemingly as normal as normal can be under pretty extraordinary circumstances,” says Adam Streisand, the lawyer who represents Katherine Jackson and a frequent visitor to the compound where she lives with the children. He provided an account of life inside their guarded world in an interview. The large Jackson family, including eight of Michael's siblings and their families, has been a source of emotional support for the children, who frequently play with their cousins, Streisand says. The three youngsters have seen Michael Jackson's final concert movie, “This Is It,” but their grandmother, still devastated by the death of her son last June 25, has not watched it. Prince, whose birth name is Michael Joseph Jackson Jr., is the eldest of Michael's children. At 13, he has developed an interest in filmmaking, and his brother, sister and cousins have been starring in their own home movies. “They have props and sets, and one of them acts as director. They all have roles,” says Streisand. Recently, a snippet of film was leaked to YouTube showing Paris and Blanket in what might have been scenes from one of their movies. Katherine Jackson told the Daily Mail that Paris, who has a photo shrine to her father on her wall, wants to be an actress. The children love going to the movies, especially action and fantasy films, and are usually transported by security guards who are also on duty at the family compound 24 hours a day. The Jackson kids are avid students of karate and have made friends at their karate classes. Since Michael's death, the children have continued the home schooling that had been their routine when he was alive. Streisand says a room has been set aside in a building at the estate and turned into a classroom where a tutor conducts classes. But in the fall, Prince will go to private school, a choice that was made by him and his grandmother. “He is ready to branch out and have a more socialized experience,” Streisand says. Whether his 12-year-old sister, Paris Michael, will join him is undecided, although in the Daily Mail interview Katherine Jackson suggested they all would.
