Ageing takes its toll on Kate Moss' knobbly knees

Kate Moss might be wishing she had the benefit of airbrushing during her latest night out on the town.

Arriving at Sir Paul McCartney's star-studded 65th birthday party in London, her glamorous floor length white gown featured two bold thigh-baring splits.

But the dress also revealed the 33-year-old's knobbly, wrinkle covered knees, proving that even she is not immune to signs of ageing.

Moss, who arrived toting a present for Sir Paul, spent the night partying with her pal Stella McCartney and Hollywood actress Natalie Portman.

The guest list also included her ex Jefferson Hack - luckily the former couple, who are parents to Lila Grace, remain on friendly terms.

Moss' current beau, troubled Babyshambles front man Pete Doherty, sat this party out.

Despite her advancing years, the 33-year-old has still retained her ability to be one of the world's most influential trend setters.

New research has revealed that today's music festivals are more about designer wardrobes than the acts on stage thanks to the "Kate Moss effect".

The survey, commissioned in the run-up to Glastonbury this weekend, found that a quarter of festival-goers spend around £500 on each outdoor music event.
