Has the Heather diet taken its toll on Sir Paul?
The suit is apparently the same. But it is still remarkably easy to spot the difference.
Just one look tells you Sir Paul McCartney is a little less of the man he was.
Strolling in Central London, he looked in good spirits, smiling as he chatted animatedly on his mobile phone and waving to passersby.
But his grey suit told a different story.

It looked enormous compared to the tighter fit of an identical one he was pictured in with estranged wife Heather Mills in those happy, early days of their marriage.
Photographed at Heathrow Airport with the former model three years ago, the Beatle was a fine figure of contentment.
Now his face looks gaunt, his jacket hangs from his shoulders and his trousers look a little too roomy.
Sir Paul, 64, appears to be showing the strain of his divorce from Miss Mills, which is currently going through the courts.
It has been a difficult time for the pop legend, whose four-year marriage to Miss Mills broke up last May.

He has been supported through the split by his close family and friends, but the legal wranglings are believed to be fierce.
They have involved arguments over the care of the couple's three-yearold daughter Beatrice.
Although no divorce settlement has been agreed, it emerged last week that Sir Paul has fallen out of the top 100 of this year's Sunday Times Rich List because of the amount it is predicted Miss Mills could receive.
He plummeted from his ranking as the 65th richest person in Britain last year to 102nd this time round.
He now has an estimated fortune of £725million, thanks to the predicted £100million divorce settlement experts believe he will pay his estranged wife.
Miss Mills, 39, has been winning friends in the U.S. with her apperance on reality show Dancing with the Stars.
She was eliminated earlier this week, leaving the show with a plea for viewers to follow her lead and become vegans.
