Capital's Hardest Working Pop Stars
4. Jessie J
Jessie J burst onto the music scene just over twelve months ago and has barely come up for air ever since. The catsuit-loving singer-songwriter has scored hit after hit with her debut album 'Who You Are' and had five successful solo singles in 2011, as well as featuring on James Morrison's 'Up' and kicking off her 'Heartbeats' tour back in October. In between penning songs for her next record and continuing to promote new singles like 'LaserLight' Jessie has also managed to find time to mentor a new generation of singers as a vocal coach on popular BBC One talent series The Voice UK.
