WWW- Should 54-year-old action star Steven Seagal be worried that jailed private eye Anthony Pellicano might have some dirt on him?

Celebrity detective Paul Barresi and New York attorney Robert Hantman – who reps former movie producer Julius Nasso, a pal of mobsters who’s serving a year in prison for conspiracy to extort the actor – believe Seagal might be sweating.

According to Barresi, who worked closely with Pellicano back in the last century, the imprisoned detective knows whether Seagal was involved in threats to journalists who were investigating the actor.

Hantman has filed court papers in an effort to discover if the FBI “sanitized” Seagal’s supposed sins in order to convict his client Nasso.

Barresi told me that Seagal shouldn’t take comfort in a recent vow from Pellicano – who’s serving 30 months for illegalweapons possession – that he’ll never dish on his famous former clients.

“I won’t rat. I’ll stay loyal and rot behind bars rather than divulge anything about any client,” Pellicano was quoted in another gossip column as declaring.

But Barresi told me: “I know Pellicano well, and this is a shot across the bow. It’s Pellicano saying, ‘Hey, I’m still out here, and I know where the bodies are buried.’ I would think that Steven Seagal is in the back of Pellicano’s mind.”

A PR rep for Seagal told me the actor is completely baffled by Barresi’s theories.

“He really doesn’t know what to say about this, except that things like this are very much in his past,” the rep said. “He’s risen above this and moved on to a very blessed career and life. He hoped that the legal outcome would have sufficed to bring a very stressful period in his life to a close. He’s sorry to hear that others haven’t moved on.”
