Oscar winner Colin Firth was star-struck when meeting elephant conservationist Dame Daphne Sheldrick at CBS yesterday. Firth told Sheldrick, who has spent more than 50 years rescuing African elephants, that he was a huge fan and had visited her elephant orphanage in Nairobi with his family. Sheldrick, there to promote her memoir “Love, Life and Elephants,” replied, “I loved you in ‘The King’s Speech’!” She speaks tomorrow at the Museum of Natural History.
