Hollywood insiders are wondering if Tom Cruise's powerful legal team will quash a tell-all which makes some pretty shocking insinuations about the actor's sex life.

Porn producer Paul Barresi is writing a book, "Pellicano's Enforcer," about how he allegedly helped incarcerated former private-eye-to-the-stars Anthony Pellicano protect celebs from negative stories.

Barresi neither proves nor disproves the claim, but Cruise, says a well-placed source, "cannot be happy with the story,' adding, "It's been a tough time for Cruise and my bet is that his lawyers are going to come out with both guns blazing - legally speaking of course."

Cruise's lawyer, Bert Fields, told the Scoop that the allegations made by Barresi are "utterly, one hundred percent false" and "we can prove it." He adds, "If Mr. Barresi were to publish what we have seen on that Web site, I absolutely would recommend appropriate legal action against both Mr. Barresi and the publisher." Fields also says that he's "considering" steps to have the chapter removed from the Web site.

"Nicole just wants to move on, but he won't let go," the insider told the mag. "Nicole thinks it's unhealthy for them to talk and hopes AM will finally just leave her alone."
