The Welsh wonder has had an incredible career so far, but how much do you really know about her? Find out more with our fantastic fact gallery.
Katherine Jenkins was born on June 29th 1980 in Neath, Wales.
Katherine was something of a boffin at school - she managed to pass her GCSEs and A-Levels with top marks, and passed her Grade 8 voice and piano exams with distinction.
The young K-J cut her teeth singing in school productions like Calamity Jane and Guys and Dolls.
Once everyone realised she had some serious talent, she was immediately signed up to the National Youth Choir of Wales, as well as being a member of the Royal School of Church Music Cathedral Singers. When she was 17, she landed a scholarship at the Royal Academy of Music.
As many musicians do, Katherine had to take a few less than glamorous jobs to make ends meet on the road to the top. For her, they included a little bit of teaching and even a stint as a tour guide on the London Eye!
Wearing her national pride on her sleeve, Katherine Jenkins is the go-to girl if you want the national anthem sung properly. She's performed the English and Welsh national anthems at a variety of events, from the FA Cup Final in 2008 to the London Parade of the Olympic Athletes.
Katherine is also known for her extensive work singing for British troops abroad, in much the same way as singers like Vera Lynn. In fact, it was Lynn herself who suggested to Katherine that she go out and sing for them. She has sung for the troops in Afghanistan and Iraq on several occasions.
Jenkins once performed an updated version of a Victor Borge comedy sketch alongside pianist Kev Orkian at a private birthday party. Oh, and Lionel Richie performed as well. No biggie.
Katherine became known as much for her feet as her vocal chords in 2012 when she took part in US television show Dancing With The Stars. What's more, she finished in second place!
In 2013 Katherine toured Europe with the operatic four-piece Il Divo. Fans were treated to plenty of duets on songs from both artists' varied careers.
