Members of the Royal Family have appeared on the balcony of Buckingham Palace to greet crowds gathered to celebrate the Queen's official 90th birthday.
The Duchess of Cornwall, the Duchess of Cambridge and Prince Andrew were among the royals waving to crowds.
The Queen is expected to appear later for an RAF fly-past. Thousands of people lined The Mall and gathered outside the palace ahead of the spectacle.
The Trooping of the Colour took place earlier on Horse Guards Parade as part of the second day of celebrations.
Queen will be guest of honour at a huge street party on Sunday as three days of celebrations to mark her 90th come to a spectacular close.
At 13 months old, Charlotte is almost the same age as the Queen was when she first appeared on Buckingham Palace's balcony 89 years ago.
The Queen's official birthday is set to be marked today by a Trooping the Colour parade held in her honour.
