Jackson Estate Lawyer To Sue Mann?

A lawyer representing MICHAEL JACKSON’s estate has threatened legal action against KATHERINE JACKSON’s new business partner, alleging he has no right to make money from the late singer’s legacy.

The Jackson matriarch has teamed up with businessman Howard Mann to publish a picture book called Never Can Say Goodbye: The Katherine Jackson Archives.

The book hits stores this week (begs21Jun10) to mark the first anniversary of the superstar’s death, and the pair is said to be negotiating record deals to release 273 unheard Michael Jackson songs.
