Jessie J debuts 'Not My Ex' ♫♫

Jessie J reflects on failed relationships in a soulful new cut called 'Not My Ex.' The cut is lifted off  her forthcoming album 'R.O.S.E.'

Jessica is serving straight quality and I'm here for it. Her piercing vocals are taking center stage and she's wearing her emotions. The bad news however... is that it just isn't a hit.
