David Letterman’s Mistresses Diary Details Affair

Pretty former “Late Show” staffer Stephanie Birkitt revealed in her diary that she continued having sex with boss David Letterman even after moving in with her CBS-producer boyfriend, who later allegedly tried to extort him over the affair.

Late Show with David Letterman staffer Stephanie Birkitt is seen snuggling her man.

Letterman and Birkitt enjoyed romantic hikes last fall at his sprawling ranch in eastern Montana — where he was married in March — while her boyfriend, “48 Hours Mystery” producer Robert “Joe” Halderman, stayed home in Connecticut, the sources said.

At the time, Birkitt, 34, insisted to Halderman that she and the 62-year-old Letterman had just “a platonic relationship,” a source said.

“I’m his best friend,” Birkitt told the worried 51-year-old Halderman, the source said.

Letterman was such a good “friend” that at least once a week, he also would drive Birkitt home to Norwalk, Conn., where she had been sharing a house with Halderman since he divorced his wife in 2004, sources said. The TV funnyman lived with his longtime girlfriend and their son in Westchester.

The multimillionaire comic even did his best to keep Birkitt, a graduate of Benjamin Cardozo Law School, on his payroll.

After she graduated in June 2008, he offered her a job as his personal lawyer, the sources said.

Birkitt later tried to use the generous offer to persuade Halderman to have children with her, saying she would bring in the bucks in her new job and he could stay home as a Mr. Mom, the sources said.

Halderman exploded when he read Birkitt’s diary in December and learned that she was still carrying on a steamy affair with Letterman, the sources said.

The bombshell details in the sensational case emerged as Letterman returned to the “Late Show” set for the first time since Thursday, when he stunned his audience by revealing he had had sexual affairs with female staffers and allegedly had been the target of a related $2 million extortion plot by Halderman.

A clearly chastened Letterman was greeted with thunderous applause during the show’s taping in the Ed Sullivan Theater in Midtown last night.

“Wow, that weekend went fast,” Letterman deadpanned as he opened his monologue.

Sitting down at his desk, Letterman turned serious, saying, “No, I’m not having sex” with any staff members currently, and insisting, “You can’t be victimized by criminals.”

I’m not fairly certain why, but I could care less about his seedy affairs. Two consenting adults, etc. I do feel sorry for his wife, but it’s up to her to forgive him or not. I don’t think Letterman should lose his job over it.
