And the former royal offered Elvis' daughter her villa in Spain in June so she could mourn in private the passing of her ex-husband Michael Jackson.Sir David Frost and his wife Lady Carina Fitzalan-Howard were also in attendance.The low-key affair follows stories in the media that Sarah cancelled an extravagant party amidst financial concerns - reports later denied by the Duchess' spokesperson.While hitting the landmark age of 50 might cause sleepless nights for some ladies, Sarah says she is only looking to the future."I've got children's books to write. The girls are at university, but I've got my charity work…I'm just beginning my life," she said in a recent interview.
