MUMBAI: Things aren't exactly cosy between the sheets for American porn star Jenna Jameson and New York publisher Judith Regan. Jameson's book How to Make Love Like a Porn Star was a bestseller for Reagan.

However, now Jameson has asked a federal judge in Phoenix to block publisher Judith Regan's claim to a financial stake in a reality TV deal.

Reagan has filed a countersuit that claims that Jameson signed an agreement last April giving Regan Media the exclusive right to negotiate with TV networks on any project involving Jameson.

The complaints will be heard in Phoenix Federal Court, near Jameson's home. Regan is preparing to move her Regan Books imprint to Hollywood in the hope of building a bigger TV and movie operation.

Jameson's real name is Jenna Massoli. Jameson says in court papers that her husband, John Grdina, negotiated for months with A&E - before last April - to do a reality series based on her everyday life.

Regan's counter suit says that the 2004 agreement with Jameson gives Regan Media the exclusive rights to negotiate with TV networks for a reality show. The countersuit says that Jameson violated the agreement by negotiating a contract with A&E without Regan Media.
