Twin sisters, who are said to look amazingly like Leona Lewis, have impressed the judges at this year’s X Factor auditions.

According to The Sun, Kim and Lauren Goddard, 22, impressed all four of the show’s judges and have made it through to the bootcamp stage of the show.

Sources told the newspaper that Simon Cowell was “blown away” by the girls, who perform under the name Siren.

A source said: “The twins are amazing. If Simon was blown away by Leona, he’s doubly blown away by these two.

“He even got them to sing Bleeding Love at their first audition. It was amazing.

“They’re just brilliant and they’ve got so much potential.

“They’re beautiful girls, impeccable singers and really lovely people.”

However, Simon Cowell has told the girls to go away and find their own style, rather than mimicking Leona.

The source added: “Simon has already warned them about being too like Leona because he thinks they need to be themselves.”
