Today, Her Royal Majesty Queen Elizabeth II celebrated her 92nd birthday at Royal Albert Hall with several members of the royal family, including Prince Charles, Prince William, Princess Anne, and Prince Harry, with his fiance, Meghan Markle.
She will mark Saturday with a birthday concert at London's Royal Albert Hall.
Kylie Minogue, Craig David, Sting and Shaggy are among the artists performing at the event.
Elizabeth has led the Commonwealth since she became queen in 1952.
The 14-year-old donned a navy dress, which matched her mothers, as she entered the Royal Albert Hall this evening for a special birthday concert.
The concert comes at the end of the week when the United Kingdom hosted 53 countries for the Commonwealth Heads of Government meeting.

The queen is head of the Commonwealth. The day after her birthday, Queen Elizabeth plans to start the London Marathon from a special podium at Windsor Castle, which is where Prince Harry and Meghan Markle's wedding will occur next month.
The monarch's grandson Prince Harry, who will marry United States actress Meghan Markle at Windsor on May 19, is the trust's new president and was due to give a speech at the concert.
She still carries out official engagements but her husband Prince Philip, who spent 10 days in hospital this month for a hip replacement, retired from public life a year ago.
A 41-gun salute was staged in Hyde Park while other such salutes took place in other locations, as per tradition, the Daily Mail reported.
But many on social media were left confused over how two comedians and a man who had a chance at becoming Prime Minister ended up singing at The Queen's 92nd birthday party.
