Madonna made her eighth appearance on The Late Show With David Letterman last night. The Material Girl claimed she’d never had a New York slice before. Is that even possible? Didn’t she live here back in the late ’70s/early ’80s? Did New York not have slices then? Letterman rectified the situation by taking her to Angelo’s Pizza, right next to the Ed Sullivan Theater, where the show is taped. Madge, who said she is “not a cheese person,” opted for olives and basil on her slice, but got extra points for pairing it with a martini, up.
