I must say she still looks very good and Agile for a 90 year old great grandmother. It is only right for me to wish her a Happy Happy Birthday, being a UK citizen myself.
Elizabeth was born on 21 April 1926 in London, the first child of Albert, Duke of York, and his wife, formerly Lady Elizabeth Bowes-Lyon.
There will be cake today for Queen Elizabeth at 90, and a chance for her to meet others marking the same birthday. She'll do a walkabout, as she has done so many times before, and unveil a walkway near her home at Windsor Castle just outside London.
The events on tap for the Queen this week may be low-key — by royal standards. They will also be royal business as usual: today's appearances for Britain's longest-reigning monarch include going to the local postal sorting office in Windsor and opening a bandstand. On Friday, she'll host a high-profile guest — U.S. President Barack Obama — for a private lunch.
