Ray J Claims Kim K Superstar Producer Will Testify in Kardashian Defamation Case

Last week Ray J accused Kris Jenner and Kim Kardashian of lying under oath after claiming they had nothing to do with the sale of Kim and Ray J's infamous tape [click here if you missed that].

Now Ray J is preparing to call former Vivid Video owner, Steve Hirsch, to testify...

From TMZ

The singer's lawyer, Howard King, tells TMZ ... if Kim or Kris continue denying they worked with Vivid Entertainment boss Steve Hirsch to release the tape, King's team is prepared to call Hirsch himself to testify.

King insists Hirsch could confirm the role he says Kim and Kris played in orchestrating the tape’s rollout back in 2007.

He also fired off a warning shot at Kim specifically -- saying if she hopes to one day become a lawyer, making sworn statements that aren’t true could seriously backfire and subject her to criminal perjury prosecution.

In old interviews, Hirsch -- who no longer owns Vivid -- has said Kris had no role in selling the tape.
