Jessie has also written lyrics for artists such as Chris Brown and Miley Cyrus, including "Party in the U.S.A.".

Jessie J says the album's title track, "Who You Are", is one of her proudest creations, she said the song is a positive role model for young people and I always say that I'm half-artist, half-therapist. In late 2010 Jessie J released her first single, "Do It Like a Dude" which was co-written with George Astasio, Tj Normandin, Jason Pebworth, Jon Shave, Kyle Abrahams and Peter Ighile.

MTV reported that the single is, so far, only confirmed for release in the United Kingdom. The album's fourth single was "Who's Laughing Now".
