A 14 year old singer has wowed the Britain’s Got Talent judges at her recent London audition.

Katie Thornett sang Etta James’ At Last, for the 3,000 audience members and the panel. Amanda Holden told her: “I loved it. You have a lovely quality to your voice – a bit Duffy-esque with that 60s sound.”

Piers Morgan added: “To sing like that for your first audition was incredible.”

Simon told her: “You started the song great, but you ran out of puff half-way through.”

Katie replied: “I just want to show you and other people my talent.”

An insider told The Sun: “The judges were impressed with Katie after so many terrible acts.”
