Jessie J says her third album is completely different to anything she has ever done before.

The 26-year-old singer believes she has grown up a great deal since her first offering and cannot wait to unveil a new sound on her latest record.

She told Capital FM: ''This is the album to make a change. I feel like this album is what it's about for me.

''I've learned a lot, I've had my ups and downs and I reckon the third album is the one where you have finally found your feet.''

And she couldn't wait to tweet fans after her first listen to the new music.

Jessie wrote: ''LISTENING TO ALBUM 3 RIGHT THE WAY THROUGH FOR THE FIRST TIME. I CANT WAIT FOR YOU ALL TO HEAR IT! Woooooo!''

This week, Jessie's eagerly anticipated new track 'Bang Bang' featuring Ariana Grande and Nicki Minaj debuted.

The song was written by Max Martin - who has been responsible for many Backstreet Boys hits - Savan Kotecha and Ilya.

Jessie took a break from music to star as a coach on BBC's 'The Voice' but has left the show to concentrate on her music career.
