Prince Jackson, Son Of Michael Jackson, Threatens To Tell The Truth As if the Jackson family drama couldn't get any more twisted, Michael Jackson's oldest son, Prince, is now threatening to tell the truth if the lies don't stop. The 15-year-old tweeted early Thursday morning about the return of his grandmother Katherine, about the mistreatment from his aunts and uncles (including Janet, Austin and Rebbie) and about a warning issued from his late father, who he said "had repeatedly warned me of certain people and their ways." Prince's exigency comes at the behest of his two siblings, sister Paris, 14, and brother Blanket, 10. Prince had previously remained quiet about the bizarre series of events this week, which have seen his 82-year-old grandmother reported missing, found the next day at a resort in Arizona on doctor's orders, and then losing her guardianship over her three grandchildren. Early Thursday morning, Prince tweeted, "grandma's here! #thankyougod." He then continued with shocking claims against his family members, saying that Katherine Jackson had been "lied to" and that he and his two siblings had been denied contact with their grandmother. "For this whole time, they denied us contact to our grandmother. If you continue with your lies I will continue with the truth," Prince tweeted. "As long as I can remember my dad had repeatedly warned me of certain people and their ways. Although I am happy my grandma was returned, after speaking with her I realized how misguided and how badly she was lied to. I'm really angry and hurt."
