Leona Lewis has defended her decision not to drink - insisting revellers who need alcohol to have a good time have a "stupid mindset".
The Bleeding Love singer is proud of her healthy lifestyle, refraining from eating meat or drinking booze.
And the teetotal star is baffled by partygoers who need a drink to boost their confidence - branding them "ridiculous".
She says, "I find some people's attitude to drinking ridiculous. I think it's so funny that people think you have to drink in order to have fun. It's such a stupid mindset!
"A lot of my friends are like, 'I need a drink to get on the dancefloor!' I don't need that 'help me to relax' thing.
"If I'm around my friends then I can really relax and have a good time, that's all I need. I don't need alcohol."
