Debbie Rowe -- Michael Jackson's Brothers are Greedy Slackers

Debbie Rowe is scoffing at members of the Jackson family who claim she abandoned her children for Michael Jackson's money ... saying it's a classic case of the pot calling the kettle black.

Sources connected to Rowe say Debbie expected Jermaine, Randy, Tito and Jackie to attack her when word got out -- via TMZ -- that she would fight for the guardianship of Paris and Prince.

Michael's brothers came out swinging, saying Rowe took Michael's money and then ran away from her kids and her responsibilities.

But our sources say Rowe is pissed but not surprised at the attack, insisting she never abandoned her kids. She says Michael constantly called her for parenting advice and she was always there for him and the children.

She also says Michael often told her the only sibling with any talent was Janet, and the others turned sponging off him into an art form.

Rowe -- who would also like to become Blanket's guardian -- is deeply fearful the kids have no proper supervision. She thinks Katherine is a good woman but way too old and slow to care for the kids, and she thinks Michael's siblings all couldn't give a crap and they are all bad influences.

Rowe believes MJ's brothers oppose her plan to seek guardianship because they know if that happens a huge chunk of the money Katherine gets from the MJ Estate -- more than $50K in child support -- will dry up.
