The Queen may have turned 90 last month but her birthday celebrations are not over yet.
The celebrations will continue with a major event in the grounds of Windsor Castle, from 12-15 May.
Here's all you need to know about the event.
- What's happening?
The event will tell the story of the Queen's life and reign, with a particular emphasis on Her Majesty's well-documented "love" of horses and her "deep involvement" with the armed forces, organisers say.
Spectators have been promised a "spectacular" night of music, dance and equestrian displays.
It will be held in a purpose-built arena which holds 25,000 people.
Members of the Royal Family will attend each night, while the Queen herself, accompanied by her husband, the Duke of Edinburgh, will attend the final night on May 15, which will be broadcast live on TV.
- Who's performing?
Kylie Minogue, Jess Glynne and Katherine Jenkins will be among the high-profile names to perform.
Other stars making an appearance include: Star Wars actor John Boyega, Wolf Hall star Damian Lewis and singer Alfie Boe.
Organisers say the equestrian displays will be similar to The Diamond Jubilee Pageant in 2012, which took place in the same venue.
- Can I buy tickets?
Tickets, priced from £55 to £195, sold out within hours when they went on sale last November.
- Where can I watch?
You can watch live coverage of the star-studded event, hosted by Ant & Dec, on ITV from 8.35pm on Sunday.
