This photo of Princess Diana was released by WENN during the engagement of PRINCE WILLIAM to his fiancee KATE MIDDLETON in 2010. William presented Kate with his mother's engagement ring - to mark his devotion to his "special" wife-to-be. On Tuesday (16Nov10), the British royal announced he proposed to his longtime love Middleton on holiday in Kenya last month (Oct10), and the couple is planning to wed next year.
