It's always frustrating to communicate via voice-mail, especially when you're a hammered celebrity, like Pat O'Brien.

O'Brien, who entered alcohol-rehab on Sunday, allegedly left a series of messages for a female acquaintance last week that described, in detail, his plans for a Keith Richards-like "get together" involving her and another woman.

"Let's just [bleeping] have sex and fun and drugs and go crazy," says a male voice.

Yesterday reps for "The Insider" would not comment on widespread attribution of the voice to O'Brien.

The tape describes in graphic detail just how "badly" the caller wants various activities that involve, gosh, all parts of the woman's body.

"I'm so into you, Betsy is so f——ing jealous," the voice claims in one message. "I know you want me, but you have to be with Betsy, too."

"The Insider" host has one child with his wife, Linda.

Sadly, by the final message, Betsy seems to have pulled out of the threesome.

Says the caller: "Get another woman up, hire a hooker, let's get crazy, get some coke and if you get this message, if you agree with this, just look at me and say yes."
