After all he's been through in recent times, Sir Paul McCartney could be forgiven a few worry lines.
It seems, however, that the 65-year-old singer may not have been happy with his looks.
Friends have claimed that shortly before an operation in London to correct a heart murmur, he had cosmetic surgery in New York to rejuvenate his face.

The work, they say, was to remove crow's-feet from around his eyes, and also sagging skin from beneath and above them.
The result is a face that appears much younger and stress-free.
Photos taken earlier last year showed how his divorce from Heather Mills was taking its toll.
Sir Paul frequently looked worn down, with excessive wrinkling around his eyes.
While the operation to increase blood flow to his heart in September will undoubtedly have helped with the movement of blood around his face, giving him a rosier complexion, that would not explain the disappearance of the saggy skin.
Some cosmetic surgery experts have said he appeared to have the tell-tale signs of work to improve his looks. London plastic surgeon Alex Karidis said: "His lower eyelids look different. On the newer pictures, that area is a lot clearer."
He added that the pictures "would suggest that there has been some surgery to take some of the excess skin away from the eyelids.
"He definitely has less skin above both eyes than before."
But plastic surgeon Dr Lucy Clancey was more cautious, saying: "There is an ever so slight improvement.
"I would also say that he has lost a lot of weight in between the two pictures."
Sir Paul's spokesman rubbished the notion that he may have had surgery.
As the singer's divorce edges closer to a potentially ruinous court case next month, his relationship with Miss Mills has never been more fraught. The pair had a series of rows over Christmas.
