Debbie Rowe, surrogate mother to two of Michael Jackson's children, has filed legal papers stating her support for the new joint guardianship arrangement. However, she also stated that she would intervene "Should the arrangement sought by TJ Jackson and Katherine Jackson become untenable, unstable, unsafe, or in any way contrary to the best interests of the children."  The documents were filed in L.A. County Superior Court, saying she has reviewed the co-guardianship application and signed off on the deal to share parenting responsibilities for Paris, Blanket and Prince.
