The 27-year-old singer posed for the May cover of UK Glamour and appears to be back to her old healthy self after a difficult 2010, following the collapse of her marriage to footballer Ashley Cole and a life-threatening battle against malaria.
The Girls Aloud star told the magazine that she is currently enjoying a break from her usually hectic schedule.
She said: 'I really plan to not plan. I've had my life mapped out for the best part of 10 years, so for now I just want to enjoy myself and live in the moment.'
The Geordie-born singer also spoke about her stay in the US and said she was shocked by the nation’s obsession with health regimes as she does not follow one herself.
She said: 'I don't have a regime that I regularly stick to. I honestly don't have one.
'But the TV out here [in LA] is non-stop with adverts for the latest health craze. People give themselves too much of a hard time with stuff like that – just do it if you want to.'
