Former pop singer Lulu has admitted that her youthful looks are partly down to Botox – and that she will be giving up the wrinkle-busting injections because too much of her face becomes ‘immovable.’

“I used to have Botox and I thought it was fantastic at first,” Lulu explained to British magazine Good Housekeeping. “But it quickly fades. Too much of it makes your face immovable and it doesn’t actually help you to look young so I stopped.

“I would consider [cosmetic] surgery in the future but, as with everything, it is a case of going to the best person and having it done in moderation. I never go out looking like a bag lady and I even put on lip gloss to walk the dogs. I’ll try to look my best until I’m 80 and beyond, God willing.

“I don’t wake up in the morning and say ‘Oh, you gorgeous thing.” But sometimes you put on the right outfit, your hair’s looking just right and your skin’s glowing and you think, ‘You don’t look bad for an old girl’

“I’m careful with my diet, eating three healthy, balanced meals. But I always make sure I have a daily treat, whether it’s a piece of chocolate, a cookie or a bit of dessert.”
