Although she claims her half century is approaching, Nancy Dell’Olio is still a twentysomething WAG at heart,
For her latest social appearance, she turned up apparently braless in a tight-fitting chocolate silk dress which showed off large expanses of leg.
Miss Dell’Olio, former companion of ex-England football manager Sven-Goran Eriksson, is now in a relationship with theatre director Sir Trevor Nunn, 71.
However he appeared not to be in evidence when she attended the summer ball at the Serpentine Gallery in Kensington Gardens, West London.
The Italian-American property lawyer’s true age has long been the subject of speculation.
But earlier this month she said she was looking forward to her 50th birthday in August.
Interviewed on Radio 4, she said: ‘Age doesn’t mean anything and I’m very proud to be turning 50. I’m turning into a different stage in my life and I’ve never felt as good.’
Ms Dell'Olio plans to spend celebrate with 'two days of partying in Puglia, in Italy, where I spent many of my childhood summers', she told online community www.high50.com.
She added: ‘Barack Obama turns 50 this year too. I have something in common with him: everyone’s always asking to see our birth certificates!’
Other celebrities at the annual star-studded summer society bash, which was hosted by Burberry, included the label’s creative director Christopher Bailey, Tara Palmer-Tomkinson, Yasmin and Simon Le Bon, Erin O’ Connor, Laura Bailey.
All money raised from the party will go to the gallery’s internationally acclaimed contemporary art, architecture, design and education programmes.
