Marlon, Tito, Jackie Jackson -- Unlike Jermaine & Randy, We're NOT Money Grubbers

Unlike Randy and Jermaine Jackson ... Marlon, Tito, and Jackie have NEVER tried to suckle from the teat of the Michael Jackson estate -- this according to well informed sources.

We're told the financial motives of Randy and Jermaine have splintered the family -- because the other siblings have refused to ask the estate for a handout since Michael died.

If anything, the factionalization shows how sharply divided the family has become after being left out of Michael's will.

As for TJ's new role as temporary guardian of MJ's kids -- we're told Tito, Marlon, and Jackie fully support the court's decision.
