McCartney, 65, wrote in a message on his Web site that reports he had heart surgery were "completely distorted" and "untrue."

He said he wanted to clear up the rumors because friends have been calling and texting him to see if he is OK.

"I hadn't seen the report so I was puzzled by so many inquiries about my health. So I think it's a good time to put this rumor to rest," McCartney wrote. "What happened was, over a year ago, during a routine medical examination, there was a minor irregularity which I needed to have tests for and which I have now been assured is completely fine. The media have only just recently reported an exaggerated version of this and that is why people have been asking me if I am OK. So this is where the story has come from. The media reports have, as usual, completely distorted the story, calling it an angioplasty, which is entirely untrue."

The former Beatle also said he feels great and "passed my most recent medical with flying colors."
