MICHAEL Jackson’s defense is trying to find out if Court TV’s Diane Dimond has been nosing around prosecutors.

Newly released documents show that Jackson’s lawyers cast a wide net of “discovery” – prosecution evidence entitled to the defense – in July, and asked for any notes made by DA Tom Sneddon of talks he might have had with Dimond.

The TV reporter, who has been a thorn in Jackson’s side going back to the 1990s in her years at “Hard Copy,” scored the best Jackson story of the year so far.

Back in mid-June, she obtained previously secret documents that fully detailed Jackson’s $25 million civil settlement with young accuser in 1993.

DA Sneddon has so far denied the defense’s Dimond mining expedition – claiming Jackson’s request fell outside the scope of discovery.
