Jessie J overwhelmed by sudden fame

Jessie J feels like fame has taken over her entire life.

The 22-year-old singer says celebrity has come so quickly - with her scoring a number two hit with her debut UK single 'Do It Like A Dude' and being named recipient of the Critic's Choice prize at the 2011 BRIT Awards last December - she is still adapting to it, but feels she has the power to stay in the spotlight for her fans.
