Michael Jackson's ex-wife Debbie Rowe has filed papers showing her support of the new guardianship arrangements of her children.

Debbie gave birth to Prince, 15, and Paris, 14, while Blanket was the product of a surrogate carrier.

Katherine Jackson had lost guardianship of her three grandchildren when she disappeared for 10 days but now a new arrangement has been put in place for her to share parenting duties of the brood with grandson TJ Jackson, 34.

And TMZ reports that Debbie filed documents in Los Angeles Superior Court on Thursday saying that she had reviewed the co-guardianship application and signed off on it.

But she made it clear that she would intervene if things didn't work out.

'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, Ms. Rowe will seek court intervention,' the documents stated.

Debbie says that her primary concern is for the health, safety and well-being of her children.
