Kate Middleton and Prince William Attend Queen Elizabeth’s

The birthday celebrations just won’t end for Queen Elizabeth ll!

More than three weeks after turning 90, the royal family member was treated to a special party at Windsor Castle with more than a few familiar faces.

After arriving in a horse-drawn carriage, the Queen received a kiss from her son Prince Charles as they walked inside. Once she took her seat, the birthday girl was able to watch the Royal Windsor Horse Show.

Sitting nearby the Queen was Kate Middleton who looked radiant in a white Dolce & Gabanna dress that was partially covered by a red Zara jacket. Prince William and Prince Harry were also close by and were spotted wearing the Windsor Uniform.

Guests that also included Princess Beatrice and Princess Eugenie were treated to much more than a horse show.

Dancing With the Stars alumna Katherine Jenkins, “Your Beautiful” singer James Blunt and Helen Mirren were also on-hand to perform at the royal gathering.

The past several weeks have been filled with special royal moments in celebration of Queen Elizabeth’s big birthday.

Whether posing for official portraits with her great grandchildren or hosting lunch for President Barack Obama and First Lady Michelle Obama, the Queen hasn’t exactly slowed down.

And for those wondering how the Queen celebrated her actual birthday, E! News previously reported that she walked around Windsor Castle to accept gifts and well wishes from citizens.

She later traveled to Castle Hill, lit a beacon in Windsor and cut a piece of delicious cake from Chocolatiers at Cadbury World. Yes, even the Queen needs some chocolate on special occasions.
