Celebrity Justice reports that CNN’s Larry King was served with a subpeona to testify in the Micahel Jackson Circus. Trial. The Michael Jackson Trial.

CJ says King got hit with the subpeona while leaving a Beverly Hills newsstand Friday morning.

Why? Well that’s a bit complicated:

We’re told King will testify about a conversation he allegedly had with Larry Feldman and book publisher Michael Viner at Nate and Al’s, a landmark Beverly Hills deli.

Feldman’s the attorney who represented Jackson’s 1993 accuser, and who has also had many meetings with the current accuser and his mother. Last year, Feldman told “Good Morning America” that he believes the latest boy’s story.

While Feldman has denied he told King anything damaging about the accuser and his family, sources tell “CJ” that the book publisher, Viner, contends Feldman made unflattering comments about the accuser’s mother. And it was Viner’s impression from the conversation that the mother wanted money.
