Queen Elizabeth II, Britain’s oldest and longest-serving monarch, celebrated her 90th birthday Thursday. 

The Queen emerged Thursday morning to cheering crowds.

She’s expected to celebrate at a private party, with about 60 guests, Thursday night. 

Her official birthday portrait was published overnight on Thursday. The portrait showed the Queen posing with Princess Charlotte and Prince George, along with some of her other grandchildren and great-grandchildren.

Another portrait was released of the Queen with four of her beloved dogs. 

The photographs were taken by American Annie Leibovitz. 

“Having lost my mother at a very young age…,” said Prince William.  “…It’s been particularly important for me that I have had somebody like the Queen to look up to, and who has been there, who has understood some of the more complex issues that, you know, when you lose a loved one,” he continued. 

The Queen was serenaded by all ages the past week. 

She’s the world’s most photographed woman, almost never shows emotions in public, but loves a good joke. 

Thursday morning Britain said “Thank You, Your Majesty,” with a 21 gun salute.
