Amy Winehouse blew off the photocall for Nelson Mandela’s 90th birthday concert in London this weekend. And this was no small affair: Will Smith, Annie Lennox, and Brit singers Sugababes and Leona Lewis were among the dozens of big-named celebs that managed to show up.

Where was Winehouse? I know, the first thought was “Well the poor dear’s been in the hospital, fighting early emphysema and whatnot. Who knows if she’s up to it?” Nope, Amy was stocking up on some serious booze. Well, serious for most of us. It’s more like mother’s milk to her.

Amy Winehouse was spotted shopping for alcohol and sweets today instead of joining her pop contemporaries at a photocall for Friday’s Nelson Mandela concert.

Although the troubled star confirmed she will sing at Mandela’s 90th birthday concert - despite being diagnosed with early stages of emphysema - her snub will no doubt unsettle organisers and fans ahead of the highly-anticipated gig in London’s Hyde Park.

The 24-year-old was released from hospital on Monday after doctors confirmed she has scarring of the lungs which can cause emphysema, but it is treatable.

Despite pledging to honour her live commitments at both Glastonbury and the Mandela concert yesterday and spending an hour-and-a-half in rehearsals since leaving the London Clinic, Winehouse was a no-show today.

Instead she visited her husband Blake Fielder-Civil at London’s Pentonville Prison, before stopping off at an off licence for some Jack Daniels whisky and vodka and a packet of sweets.

I’d place the odds of Amy Winehouse actually showing up to perform at 10,000 to one. And I’m guessing I’ll have no takers for that bet.

Amy Winehouse is really a do-it-yourselfer though, isn’t she? Most celebs would send an assistant or some random street urchin to buy their alcohol and fetch their drugs. But Winehouse knows how to keep it real. That means ignoring Nelson Mandela and visiting her jailbird husband, then going home to get soused before falling asleep with a needle still stuck in her vein.
