Daisy Clark, 18, from the UK.
London - She is a teenage singer who has only ever left her home county of Cornwall twice.

But Daisy Clark is set for international stardom after nearly six million people around the world watched an online video of her singing in her bedroom.

The 18-year-old posted a recording of her acoustic version of Olivia Newton-John’s classic song Hopelessly Devoted To You from the musical Grease in September.

Within weeks it was seen by executives from the Warner Bros record label, who offered to release the song professionally.

Clark, from Newquay, who recently finished a college course in music performance, had only ever left her home county to visit neighbouring Devon and go on a family holiday to Greece before the video “exploded” on a website that offers a platform to unsigned and independent music artists.

She said: “Mum and I watch Grease together quite a lot. She is really into my music and this song was stuck in my head. I never thought I would get so many views.”

Clark, who went to Truro College, taught herself to play guitar and piano and said she is unable to remember a day when she hasn’t sung. At just 13 years old she started writing her own music, inspired by the likes of pop stars Taylor Swift and Ed Sheeran.

Over the past few years she has built a fan base in her home county and online, with videos of her own songs and covers garnering more than 10 million views across social media.

She added: “The past few months have been out of this world.”

Her take on Hopelessly Devoted To You has been released on iTunes and Spotify.
