The 41-year-old singer admits to having regular Botox injections in her forehead because she hates the way she looks without the skin-smoothing injections.

She said: 'Without it, my frown scares me, let alone everyone else. I get it from my mum who has a perma-frown. It's a family trait.

'So I prefer to get rid of it with Botox in two places on my forehead. I've been having it since 2003.'

The 'I'm Outta Love' star ' who filed for divorce from husband Wayne Newton in April after three years of marriage ' also admitted she hasn't ruled out undergoing further procedures in the future, though she is more comfortable with herself than she used to be.

She added: ' would have surgery if I felt I needed it. I think it can be addictive if you have poor self-image, but I'm alright with the way I look, although it's taken a long time to get here.

'Everything I've been through has affected my confidence. It's all chiselled away at my core. But there's always putty to mend it. I'm definitely growing more comfortable in my skin.'
