The Queen is set to attend a star-studded concert to celebrate her 92nd birthday.
Shaggy, Sting, Sir Tom Jones, Craig David and Kylie Minogue are among the artists who will take to the stage at the Royal Albert Hall in central London.
The Queen and members of the royal family will be guests of honour at the celebration, which is being billed as The Queen's Birthday Party.
Prince Harry is expected to speak at the event, in his new role as president of The Queen's Commonwealth Trust.
Organisers say the concert, coming at the end of the week when the UK hosted 53 countries for the Commonwealth Heads of Government Meeting, will have a strong Commonwealth flavour.
The Royal Commonwealth Society, which has the Queen as patron and is 150 years old this year, has put the event together.
The Queen's Commonwealth Trust, which also has the monarch as its patron, is a youth charity working in education, sport, health and the environment.
The idea is that it helps to fund, champion and connect young leaders who are working hard to make a difference in the world by sharing their stories and inspiring others to join.
