In a tape she made just months before her death, Princess Diana had reportedly advised Prince William's future-wife, now Kate Middleton, to strive for her marriage to survive the constant public pressure.
Diana had also advised the couple that they should always cherish their children.
A close friend of the Princess of Wales told a US magazine that the tapes were made by Diana for her son because she feared for her life, News.com.au reported.
Lana Marks, who designed handbags for Diana, told another publication that Diana had discussed with her in great detail what she wanted for William in terms of a wife, children and what she wanted for his future.
Marks asserted that the contents of the tape are uncanny and they are exactly what the pair had talked about.
