Stephanie Birkitt, David Letterman’s galpal, may not be commenting on the extortion scandal—but her 90-year-old grandma is. Birkitt and Letterman “joked and kidded around,” but “they were just good friends,” she tells the New York Post. “She worked for Dave for 11 years. She said she never had sex with him.” And granny is no fan of alleged blackmailer Robert “Joe” Halderman.
“I think she was stupid to go out with him,” she continues. “People make mistakes and that was one of hers. Joe was a mistake.”
