Queen Elizabeth II’s 90th birthday celebrations this year will witness celebrations in May, and will come to an end with The Patron’s Lunch in June. The British monarch has already turned 90 on April 21, her real birthday. Her official birthday weekend will be celebrated all over the country in June. The official celebrations will kick off with a 90-minute minute long extravaganza with 900 horses and more than 1,500 riders and performers at Windsor Castle.

The event will be held every evening from May 12 to May 15, and the queen will attend the final evening. It will be similar to the Diamond Jubilee horse pageant at Windsor in 2012. However, this time there will be video projection and theatrical lighting. All the 25,000 tickets for the show sold out as soon as it went on sale in November.

ITV will broadcast the final night live in a two-hour program hosted by Ant and Dec. Gary Barlow and Shirley Bassey have joined the impressive line-up of stars to participate in the queen’s 90th birthday celebrations. Other performers include Kylie Minogue, Katherine Jenkins and Jess Glynne.

More than 900 horses and 1500 participants will join the celebrations, which will tell the story of the Elizabeth’s life from her birth in 1926 to her coronation, and her reign spanning 64 years. Ant and Dec said they were honored to host the special celebrations. Meanwhile, Jenkins also was excited and honored to be participating.

A list of other stars scheduled to participate include Andrea Bocelli, Alfie Boe, James Blunt and Beverley Knight. Those who will take to the stage include “Star Wars” famed John Boyega and Jim Carter, Martin Clunes, Damian Lewis, Helen Mirren and Jennifer Saunders. Guests will also be treated to performances in the arena like the Royal Cavalry of the Sultanate of Oman. Besides, the finale night will be attended by members of the royal family.
