The Princess of Wales surprised Eurovision fans last night as she took part in a short, instrumental piano performance in the opening sequence of the competition final.
Kate showed off her musical skills as she featured in a group performance of last year's Ukrainian winning entry, Stefania.
She joined a range of British contributors, including Lord Andrew Lloyd Webber, Sam Ryder, Ms Banks, Ballet Black, Bolt Strings, and Joss Stone.
The Princess' performance was recorded earlier this month in the Crimson Drawing Room of Windsor Castle.

In a message shared on the Prince and Princess of Wales' Twitter account, the Duchess said: "A pleasure to join Kalush Orchestra in a special performance of last year's winning Eurovision entry. Enjoy the show Liverpool."
This year's competition is being held in the northern English city on behalf of Ukraine after Kyiv was unable to host the contest due to Russia's invasion.
While Kate's performance was pre-recorded, in the auditorium a troupe of drummers joined Kalush Orchestra on stage.
Around 160 million people are thought to watch the final across the world.

Rumours of a surprise at the contest have been growing all week.
However, news of the Princess' involvement managed to remain secret until the opening sequence began.
Kate was wearing a blue Jenny Packham dress for the performance.
In a touching gesture, she also wore a pair of earrings owned by the late Queen.
Twenty-six acts performed at the M&S Bank Arena in Liverpool.
The UK’s Mae Muller closed the show with I Wrote A Song.
She finished second from bottom on the night, only beating Germany.
