It would seem that David Letterman has done some “creepy things”, and much to his chagrin, someone knew about it.

On last night’s episode of Late Show with David Letterman, Mr. Letterman revealed that he had been the target of an extortion attempt by someone who was later revealed to be Joe Halderman, a producer on the CBS series 48 Hours.   Mr. Halderman had attempted to blackmail Mr. Letterman for $2 million dollars over evidence had of the late night talk show host having affairs with staff members of his series.  Mr. Halderman threatened to write a screenplay and book about the evidence he had, and even after asking for the $2 million, he did not guarantee that he would no go forward with this projects.

Mr. Letterman worked with his attorney and the New York City prosecutor’s office to gather evidence about the case, and after three meetings with the gentleman, Mr. Letterman did give Mr. Halderman a fake check for the $2 million.  Yesterday morning Mr. Letterman went before a grand jury to testify in the case, and Mr. Halderman was arrested later in the day.

During the course of telling this story, Mr. Letterman did not allude to when these affairs with staff took place, but he did use several plurals that insinuated that there had been more than one.

In March of this year, Mr. Letterman married Regina Lasko with whom has been dating since 1986, and they have a 5-year-old son, Harry, together.

Mr. Letterman ended the story by saying these would be his only comments on the situation, which is not unusual as he is a notoriously private individual.

UPDATE: RadarOnline has learned that Joe Halderman lived with with one of the women that David Letterman had his affair with.  The New York Daily News was able to dig up that Halderman once lived with Letterman’s assistant, Stephanie Birkitt.  The affair is said to have ended six years ago, before Mr. Letterman had his son Harry, or married his wife.  He was, however, living with her at the time.  Ms. Birkitt is still employed by Mr. Letterman.

All of this is supposition at this time as to if it was Ms. Birkitt, but the evidence seems fairly strong.
