Heads were turned when Henry Kissinger shared a cozy meal with Sherry Lansing, the former CEO of Paramount Pictures and an ex-president of 20th Century Fox, at the Four Seasons Restaurant on Friday. Witnesses said Lansing, 67, and the 89-year-old former secretary of state — who are both married — looked friendly over lunch in the Pool Room, occasionally touching across the table. But a spokesman for Lansing told us: “They’ve known each other since Ms. Lansing was the president of 20th Century Fox in the early 1980s. He is like a brother to her. In fact, Ms. Lansing and her husband, William Friedkin, are friends with both Dr. Kissinger and his wife, Nancy.”
