The wife of McFly's Tom Fletcher has been cast in The London Musical Theatre Orchestra's production of A Christmas Carol, which takes place on 19th Decmber at the Lyceum Theatre, London.
And it's a family affair!
Giovanna's sister-in-law, musical theatre star Carrie Hope Fletcher, has also been cast in the Christmas spectacular.
Mother-of-two Giovanna is playing Mrs Crachit, while Carrie will star as Emily.
The lead role of Scrooge is played by Robert Lindsay.
This concert marks the London debut of the production by Alan Menken and Lynn Ahrens, based on the Charles Dickens classic, which has already been a huge success over on Broadway.
It marks Giovanna's professional concert debut, although we all know she's an a-mazing singer thanks to videos posted to YouTube.
