Simon Cowell says he’s delighted with the results of Susan Boyle’s first day in the recording studio.

The 48-year-old Scottish church worker – who became an overnight global internet sensation on YouTube after auditioning for ITV show Britain’s Got Talent – has recorded her first track.

Simon told The Sun: “I’ve cut one track with her and she sounds fantastic on record – she’s so good, the album is not just going to be show tunes, we’re going to take our time with this.”

Susan is working on her album in between starring in the Britain’s Got Talent tour.

She was pictured looking healthy and happy on Thursday as she attended a meeting with Sony Music bosses.

The singer was admitted to the Priory clinic after coming second to dance troupe Diversity in the TV contest, but left five days later. She was said to be exhausted and suffered what her brother described as an anxiety attack.
