Effortlessly turning in elegant pose after elegant pose for the HELLO! cameras, the 44-yearold classical artist is perfectly at home taking centre stage in our exclusive interview and photoshoot.
But when it's time to take a break, she pulls on a towelling robe and warm slippers, sips a cup of tea and chats to us in her soft Welsh burr.
It's those two sides of her personality that have made Katherine so popular, selling more than eight million albums over a 20-year career.
Ahead of her annual Christmas concert at her favourite venue, London's Royal Albert Hall, Katherine who has performed with some of the greatest singers of all time, including Dame Vera Lynn and Andrea Bocelli - reveals that she hopes to sing soon alongside a very special guest star: Aaliyah, her nine-year-old daughter with husband Andrew Levitas.
"Suddenly, out of nowhere, she's performing," she tells us. "She's really enjoying musical theatre right now and has won one of the main parts in a show, where she has a song.
"I asked her if she wanted me to teach her the song, so we had our first singing lesson and I was in my element. I was thinking: 'This is amazing.' It will take a while, but I would love to do something with her in the future." For now, Katherine is looking forward to her Christmas concert on 11 December, when she will sing a selection of festive favourites such as Silent Night and Joy to the World with some surprise guests.
"It's so special because the Royal Albert Hall is my favourite venue in the entire world," she says.
"It's especially amazing at Christmas. We have a full orchestra and choir, and we always end with everyone in the audience standing up to sing something like O Come, All Ye Faithful. That's an amazing thing to see - everyone getting in the spirit together.
