Alexander star Colin Farrell's ex-girlfriend, former Playboy Playmate Nicole Narain, will receive a $3 million advance payment if their sex tape is released.

Farrell, meanwhile, has sued Narain to try and stop the release of the sex tape, which they had made three years ago during a brief romance.

According to documents posted on website thesmokinggun.com, Narain signed a deal with the Internet Commerce Group (ICG) in October 2005, for a seven-figure payout to distribute the 14-minute video. The agreement guarantees Narain $100,000 whether or not the explicit video can be marketed, and also calls for her legal fees to be paid up to $60,000.

Farrell is seeking general and compensatory damages, as well as an injunction prohibiting the promotion and sale of the tape.

U.S. Superior Court Judge Elihu Berle quashed Narain's request to have the case dismissed on Monday and advised her lawyers to file a response to Farrell's suit instead.
