Though David Letterman apologized for the tabloid media frenzy (related to a $2 million extortion attempt) that's now greeting his staffers on Monday night, he might need to apologize to his staffers' families too—the Post went to the New Hampshire assisted living facility to ask the 90-year-old grandmother of a Late Show staffer/alleged Letterman lover some questions! Stephanie Birkitt's grandmother Irene Boyle said that Letterman "and Stephanie have always had a good relationship. They joked and kidded around... They were just good friends... She worked for Dave for 11 years. She said she never had sex with him."
