Lester seemed agitated when he spoke with News of the World, expressing concern for Jackson's three kids and complaining he hasn't seen them.
We asked if he might go to court to try and force the issue. His answer -- there's "absolutely nothing malicious" about his intentions and it's "highly unlikely" he'll go to court.
As for whether the Jackson family has shut him out of the kids' lives ... Lester wouldn't answer.
Katherine Jackson's lawyer, Londell McMillan, passes this off as a "genetic lottery attempt."
