We reported last night that David Letterman was the victim of a $2 million extortion plot and we have now discovered that according to New York public records, Stephanie Birkitt, 34, a former intern on The Late Show, lived with the accused extortionist Robert Joe Halderman, a CBS 48 Hours producer, and may have unwittingly fed him the information through the pages of her diary, photos and personal correspondence.

The 51-year-old Emmy award winning producer (view photo) was reportedly strapped for cash because of $6,000 monthly child and spousal support payments.  Father of an 18-year-old and an 11-year-old children, he divorced his wife Patty Montet in 2004.   He was arraignment on Friday afternoon on a charge of attempted grand larceny in the first degree, punishable by up to 5 to 15 years in prison.  He entered a plea of not guilty and bail was set at $200,000.

According to reports, a copy of Birkitt's private diary was passed to an undercover agent by Joe Halderman prior to his arrest in Manhattan.  It provided details of office affairs and other specifics that could potentially damage the career of Letterman.  According to TMZ, Birkitt is one of the women who engaged in an affair with her boss, but ended it in 2003, prior to the birth of Letterman's son.  New reports suggest the affair was still going on in August 2009 - see details here.

Born in Plymouth, New Hampshire, Birkitt graduated from Wake Forest University in 1997 with a major in history and a minor in communications.  Her younger brother Johnny is a field producer on ABC's Dancing With the Stars.

Birkitt began working as a page for CBS New, 48 Hours, and The Late Show while still in college in 1996. She spent a short time as an associate producer on segments for correspondent Erin Moriarty but soon decided that she wasn't a news hound.  That was when Letterman hired her as a personal assistant.  She was initially brought on to handle his charities and his Indy car racing team but her duties expanded over time.

Birkitt's role eventually gained her some on-air time, including reporting on the Winter Olympics in 2002 and 2006.  She appeared in various stunts and comedy skits over the years and handed out prizes for segments of Stump the Band, Audience Show and Tell, and Know Your Current Events.  Dave often called her 'Vicki' on stage and apparently in a standing joke, she called him "Mr Carney' - see video below.

Birkett went on to the Benjamin N. Cardozo School of Law in New York City beginning in 2005 and passed the Connecticut bar exam in February 2009.

Another former girlfriend Holly Hester has come forward.  The 1990's intern for Letterman when he was with NBC, claims they carried on a one year affair and spent a good deal of time in his secret bedroom above the Manhattan studio set that Dave referred to as "the bunker".  She said of the affair, "I was madly in love with him at the time.  I would have married him.  He was hilarious."

Letterman married his long-time girlfriend Regina Lasko in March 2009.   They have a son Harry.   View family photos here.
