Miss Knox, 21, or Foxy Knoxy, as she styled herself on her website, is known to sing in jail to pass the time.

During breaks in a pre-trial hearing, she sang hits by the band Feist, the Sun newspaper claimed.

A source at the court in Perugia, where Miss Kercher was found murdered, told the Sun: “During the hearing she never said a word.

“But outside when there were breaks for water and coffee she was smiling and singing. She was also huffing and puffing a lot - I think it was because it was a long day. It was a song by Feist and she said she sings to relax and deal with her stress.
