Did anyone know that Micheal & Janet Jackson had a half sister? see details below?

I guess all the Jackson kids have a half (illegitimate) sister? Her name is Joh'Vonne Jackson, she is 31 years old and lives in Las Vegas with her dad, yes Joe Jackson. Her Mother is Cheryl Terrell and was a fan that Joe had an affair with. Joh'Vonne works at the Las Vegas McCarran International Airport. None of the other Jackson Siblings have any contact with her because their Mother has asked them not to. Interesting tidbit of information. Many of them are jealous of the love and affection Joe has "lathered" on her as he has NOT given them any.
