A pair of Spitfires will fly over the white cliffs of Dover to celebrate Dame Vera Lynn's 100th birthday on Monday.
Known as the World War Two "forces' sweetheart", Dame Vera's photograph has also been projected onto the cliffs.
Asked for her advice on how to live a long life, Dame Vera told BBC Radio 2: "Be active to your full capabilities.
"Keep interested, read books, watch television and try to keep in touch with life and what people are doing, seeing and enjoying."
She added: "While you can do that, I hope you will continue."
