The 39-year-old classical crossover star has taken inspiration from the world of film for her upcoming 14th studio release, which will drop on 17 April followed by a UK tour early next year.
She said: "I've always loved movie soundtracks. I wanted to create an iconic movie moment with this record - all the best film musical themes that we know and love, all together on one album.
"The last few albums I’ve made have been inspired by what's happening in my own world. This one in particular was inspired by the things that were going on around me.
"Having played my first movie role last year, it felt like a natural transition for me.”
Katherine - who took on the role Millie in 'Minamata', directed by her husband Andrew Levitas - has also teamed up with Luke Evans for a medley of 'Somewhere/Tonight' from 'West Side Story'.
She added: "'West Side Story' has always been up there for me in terms of musical films. ‘Somewhere’ has been specially recorded for this album... and I’m thrilled to have Luke Evans join me on the duet ‘Tonight’.
"I loved seeing some of his TV performances last year and it was great fun to create an all-Welsh version of the duet!"
As well as announcing the full collection, Katherine has als release new single 'I'll Never Love Again' from 'A Star Is Born'.
She said: "The hope with this album is that each song conjures up an iconic image from Cinema.
"‘A Star is Born’ is quite a recent film, but the scene where Lady Gaga sings ‘I’ll Never Love Again’ is so touching and memorable that it felt completely right to include it as one of my favourite movie musical moments."
