Society is swirling with word that Leonard Lauder, the billionaire chairman of the Estée Lauder company who lost his beloved wife, Evelyn, in 2011 after 52 years of marriage, may not be a single man for much longer. Page Six revealed the 79-year-old has been dating Linda E. Johnson, the 54-year-old president and CEO of the Brooklyn Public Library. Now we are told, “They are very happy and are talking about marriage.” The news will devastate some socialites, who view Lauder, who is worth nearly $8 billion, as a huge catch. But Johnson, an attractive brunette, is rather distinguished in her own right. A Lauder rep said, “We do not comment on executives’ personal relationships.”
