Queen Elizabeth Celebrates 90th Birthday With Gun Salute, Cheering Crowds

The queen is the longest-serving monarch in British history.

— -- Happy birthday, your majesty.

Queen Elizabeth, the longest serving British monarch in history, turns 90 today.

Her majesty was dressed in a spring green silk and wool dress and coat by Angela Kelly. The queen’s hat was adorned with flowers.

The thousands of people lining the streets also waved the British flag and brought flower bouquets to the queen.

Later today, the queen will celebrate her big day with a dinner for 60 of her closest family and friends hosted by Prince Charles at Windsor Castle.

Queen Elizabeth’s grandson, Prince William, answered the question of what do you get her majesty for the milestone birthday.

“What do you give the queen? That’s like the hardest question ever so we regularly have a lot of debates,” William told Sky News. “Harry and I have decided to have a joint present this year and it makes it a bit easier when we can share the responsibility of getting it right.”

On Wednesday, three new photos of Queen Elizabeth were released. The photos, taken by famed photographer Annie Leibovitz, show the queen with her two youngest grandchildren and great-grandchildren, her beloved dogs and her daughter, Princess Anne.

Earlier in the week a new set of 10 stamps were released by the Royal Mail to mark the queen’s birthday.
