Prince William and Kate Middleton are officially the Prince and Princess of Wales.

King Charles bestowed new titles on the royal couple ahead of his coronation in May.

The announcement was made in The Gazette, the country’s official public record.

The Letters Patent passed the Great Seal of the Realm on February 13, 2023.

The new titles include Duke of Cornwall, Rothesay and Cambridge, Earl of Carrick and Strathearn, Baron of Renfrew, Baron Carrickfergus, K.G., K.T., Lord of the Isles, and Prince and Great Steward of Scotland.

The couple was given the title of Prince and Princess of Wales, as well as Earl of Chester.

In September, King Charles proclaimed Prince William and Kate's new titles, but they weren't official until now.

The announcement of the new titles comes one day after the death of Queen Elizabeth II.

The coronation of King Charles is scheduled to take place in May.
