Princess Beatrice has married Edoardo Mapelli Mozzi in secret in front of the Queen and Prince Andrew.
Prince Philip also attended the service, which took place this morning, along with about 20 other guests.
The couple's original plans had to be scrapped due to the coronavirus lockdown.
They said 'I Do' surrounded by their loved ones at All Saints Chapel in Windsor Great Park, while following all Covid-19 social distancing guidelines.
One of Beatrice's friends told The Sun : "They were obviously very keen for the Queen to come so the wedding had to happen before she goes up to Balmoral so this was a great opportunity.
"So many guests were disappointed not to make the big day but understood the reason for it.
"They are just like a normal family and had to make sacrifices like many others have up and down the country and looking forward to having a wonderful celebration when the time is right."
Beatrice, who is the Queen's granddaughter, announced her engagement to millionaire property developer Edo, and old family friend, last year and the couple planned to marry in May.
At the time, a spokesperson for the couple said: “There are no plans to switch venues or hold a bigger wedding. They aren’t even thinking about their wedding at this time .
“There will come a time to rearrange but that’s not yet.”
They had already postponed the wedding twice due to the scandals surrounding Princess Beatrice's father Prince Andrew and his former friendship with convicted paedophile Jeffrey Epstein.
Beatrice and Edoardo began dating in autumn 2018 and the elder princess of York is set to inherit the Italian title of "Nobile Donna" or "Contessa" from Mozzi's father, Count Alessandro Mapelli Mozzi when the couple eventually tie the knot.
The couple announced their engagement on September 26 2019, with photos showing Beatrice's stunning new diamond ring, which Edoardo designed in collaboration with the British jewellery designer Shaun Leane.
