Model Tamara Ecclestone at the Formula1 charity event London - Arabstoday   The fast and furious world of Formula 1 is known for its beautiful cars, and even more beautiful women. The beautiful model/presenter Tamara Ecclestone, 27, hosted a special charity event in London, and in her usual style she dazzled in a daring red and black Balmain dress, which complimented her sexy body and left little to the imagination.  She wore Christian Louboutin killer heels, which matched her pretty black clutch by Alexander McQueen. The Formula 1 event was held at the Natural History Museum in London in aid of raising funds for the Great Ormond Hospital for Children in London.  Joining Tamara was her sister Petra, 23, who looked stunning in a white Christian Louboutin dress and shoes, and Formula 1 CEO and President Bernie Ecclestone, 80.  Arriving with the ladies were businessman James Stunt, Petra’s fiancé, and Tamara’s boyfriend 37-year-old Omar Khyami.
