David Letterman confessed on the Late Show last night that three weeks ago a CBS employee left a letter & a package in his car threatening to expose his affairs with female staffers—if Dave didn’t give up $2M dollars.

Dave met w/his lawyer, who advised him to meet with the guy to see what he was talking about; they consulted with police, & ended up handing off a phony check!! The guy’s locked up, & the rest is history in the making.  Makes you wonder—how many of these plots end up successful?? Hundreds? Thousands? So much we’ll never know…

A top CBS News producer was busted Thursday for trying to shake down David Letterman – threatening to expose the late-night funnyman’s affairs with several female staffers in a movie and book.

The “Late Show” host revealed the stunning plot on last night’s show in an extraordinary confession to viewers – and admitted he had indeed slept with several women who work at the show.

“I’m glad you folks are here tonight, and I’m glad you folks are in such a pleasant mood, because I have a story I’d like to tell you and the home viewers as well,” he said, appearing to set up a comedy bit.

He went on to explain that a man identified by police as Robert Halderman, a 51-year-old Emmy Award-winning producer, found out that he was sleeping with several staff members.

Halderman allegedly threatened to expose the 62-year-old Letterman, who married his girlfriend, Regina Lasko, of 23 years in March, unless he forked over a staggering $2 million.

“This morning, I did something I’ve never done in my life,” Letterman told viewers. “I had to go downtown and testify before a grand jury.

CBS said in a statement that it was “made aware of” an ongoing police investigation involving David Letterman and an employee at ’48 Hours’,” one of the network’s news magazine shows.

“Mr. Letterman addressed the issue during the show’s broadcast this evening, and we believe his comments speak for themselves,” the CBS statement read.

Halderman, who was being held on attempted grand larceny charges, has directed dozens of “48 Hours” documentaries, from the Winter Olympics to the terrorist attacks on Sept. 11, 2001.

A “Late Show” staffer, 31-year-old Stephanie Birkitt, once lived with Halderman, according to public records.

Letterman said the shakedown started three weeks ago – when he found a package in his car.

Letterman called his lawyer, and the two men set up a meeting with Halderman, who told them he was dead serious.

Letterman and his lawyer called the Manhattan district attorney’s office, “And we say, ‘Can we run a couple of things by you guys?’

“So we took the stuff down there and they said, ‘Well, hello, this is blackmail,'” he said. The lawyer set up two subsequent meetings and gave Halderman a phony check for $2 million.

What followed was a “bizarre” and “terrifying few weeks,” Letterman said, culminating in a grand jury appearance Thursday morning, followed by Halderman’s arrest.

An insider at the “Late Show” told the Daily News last night that Letterman “did talk with Regina before he went on the air, and every indication is that they’re still together.”

All the women Letterman bedded “were consenting adults.” The insider didn’t know how many affairs Letterman had or when they took place. [SOURCE]
