Kate Middleton teases piano skills in Christmas Instagram video - and fans are excited

Royal fans are getting excited that we may finally get to see the piano skills of the Duchess of Cambridge—after she posted a teaser video on Instagram.

• The Instagram video saw her sitting down to play the piano at tonight's TV performance of Royal Carols: Together At Christmas
• Kate Middleton has been playing the piano since she was a child but we've never heard her play
• In other royal news, Prince Charles and Camilla also have a very festive surprise for royal fans

She's been playing the piano she was a child, but the Duchess of Cambridge has never played in public—but that may change after tonight.

The Instagram post shows Kate Middleton playing the piano during the Royal Carols: Together At Christmas, filmed at Westminster Abbey two weeks ago, a location that the Duchess says is special to her. And fans think the video could be a massive clue that she could be one of the stars of the show tonight.

As Kate teased the video, with no sound, on Instagram, it showed her sitting in front of a piano, in the abbey, with candles all around her.

Hundreds of thousands of fans liked the very short video clip, with one excited fan commenting on the post, "Wow! Duchess Kate playing the piano?"

While another simply said, "Honestly what can't she do? Love her".

The Duke and Duchess, who are said to be spending Christmas at home this year, unlike Charles and Camilla,  filmed the Christmas carol concert at Westminster Abbey on December 8th and they were joined by other royals including Princess Beatrice and Edoardo Mapelli Mozzi, Zara and Mike Tindall and Sophie, Countess of Wessex. 

Many wondered why the concert wasn't broadcast earlier - and some said it was because Prince William and Kate Middleton reportedly banned the BBC from airing it after the controversy surrounding their The Princes and the Press documentary. 

Kate posted other pictures of her at the abbey yesterday, showing her decorating the tree. She added to the post, "I’m so excited to be hosting Together at Christmas here at Westminster Abbey, a place that’s really special to William and me."

While the royal went on to say, "We wanted to say a huge thank you to all those amazing people out there who have supported their communities. We also wanted to recognise those whose struggles perhaps have been less visible too."

The Christmas Carol service, called Together at Christmas, will air tonight at 7.30 pm on ITV.
