ANDREA BOCELLI, the opera singer, once admitted to having serious “trouble” while performing at Princess Eugenie and Jack Brooksbank’s royal wedding, unearthed reports show.

The BBC has joined forces with Buckingham Palace to throw an extravagant party celebrating the Queen’s Platinum Jubilee.

Today, a star-studded lineup will take to the stage and offer performances of a lifetime to mark Her Majesty’s historic achievement.

Sir Elton John will dazzle crowds with his mastery of the piano, while Sir Rod Stewart will no doubt give an electrifying show.

A two-and-a-half-hour bonanza, many of the performances will be broadcast live from the Palace, with some pre-recorded acts as well.

Other musicians will also offer their services, like Queen+Adam Lambert, as well as Duran Duran, Alicia Keys, Nile Rodgers and Andrea Bocelli, Bond composer Hans Zimmer, Ella Eyre, Craig David, Mabel, Elbow, and George Ezra.

Many of them have long histories with the Royal Family, like Bocelli, who has been a particular favourite given his classical roots.

The Italian operatic legend — who is completely blind — has sold more than 90 million records worldwide and broke two Guinness World Records, and has performed in some of the world’s most renowned venues

In a candid confession, however, he admitted that he was extremely “nervous” before singing at Princess Eugenie and Jack Brooksbank’s royal wedding.

At the request of Eugenie’s mother, Sarah, Duchess of York, he sang Ava Maria and Panis Angelicus, backed by the Royal Philharmonic Orchestra.

He has described Sarah as a “very good friend… for many years”, and told the Evening Standard that she had personally invited him to Eugenie and Jack’s service at St George’s Chapel.

They met “a long time ago in a TV studio”, he said, when she knocked on his dressing room door and handed him a “biography of her life”.
