Nothing to shout about: Lulu's wrinkly knees reveal her real age
From the top of her beehive to the hem of her black studded minidress, she could pass for a woman half her age - and a pretty cool one at that.
But the knees never lie. The outfit that Lulu wore to a music festival in London revealed a pair of distinctly wrinkly joints.
Though the singer, 59, has an enviable figure and a peachy complexion, she obviously can't hold back every sign of ageing.

She is in good company, however, as Kate Moss's wrinkled kneecaps, displayed at last year's Glastonbury festival, rather jarred with the rest of her youthful image.
And Demi Moore is rumoured to have undergone £5,000 of surgery to fix hers.
But Lulu is unlikely to take such drastic action, particularly as she has
decided to stop having Botox injections on her face.
The Scottish singer announced in an interview earlier this year that she wanted to age more naturally.
Lulu recently said that she had to give up jogging in the park because her knees gave out
'I stopped having Botox because too much doesn't look good. It didn't make me look any younger and I have to move my face - I'm a singer.'
She keeps herself in shape by visiting the gym as her 'legs, thighs, belly and bum all need toning up'.
But she added in the interview that she had to give up jogging in the park because her knees gave out.
Lulu was pictured as she took a break from filming a presenting slot at the iTunes festival at Camden Palace.
