A new Londoner singer I've recently discovered is Jesse J. As a child she appeared in adverts and musical productions. However, she recognises that her talent lies in her songwriting and she's been writing songs for Justin Timberlake, Alicia Keys, Miley Cyrus and Christina Aguilera for some years. In 2011 she decided to released her own album Who you are.
Here you can listen to her song Domino.
