Debbie Rowe will wage legal war to get guardianship of the 2 kids she had with Michael Jackson ... and if she could she'd gladly take all 3.
Sources familiar with the situation tell TMZ ... Rowe is deeply concerned about the environment in the Jackson home. She likes Katherine Jackson but believes she has gotten way too old to serve as guardian ... "Katherine's not connected with the kids or involved in their lives" Rowe told a friend.
Rowe is also concerned Michael's brothers are hanging around the Calabasas house a lot and have been a terrible influence. She's complained Prince has developed a filthy mouth and is rebellious because no one is even trying to keep him in line.
Rowe is especially upset with Jermaine, who will appear on "Celebrity Wife Swap." Rowe thinks he's just plain creepy and extremely inappropriate, and wants him as far away from the kids as possible.
She feels Blanket --- the 12-year-old who is not her biological kid -- is actually the most vulnerable and most in danger.
As for Paris ... Rowe fears she's not made the kind of improvement which is necessary after her suicide attempt and wants control so she can take steps to ensure her safety.
TJ Jackson is a co-guardian ... we're told Rowe likes him but is worried that he's been on tour and away from the kids for long stretches.
Rowe will file legal docs asking the judge to appoint her guardian so she can move the children to her ranch in Palmdale CA, where she has a business raising and breeding horses.
Fact is ... Rowe has not asked the Estate for money and our sources say she's not interested in a payday. She wants the kids because she loves them and fears for their well-being.
