The veteran DJ has told the Radio Times that he has slept with around 500 women.
When asked if he could beat Bill Roache's claim of sleeping with a thousand women Blackburn said: "I did very well, but I couldn't top that."
Asked whether he got halfway in Coronation Street star William Roache's tally of 1,000 women, Blackburn, who was previously quoted as saying that he had slept with 250 women, replied: "Yes, I'm not proud of it, but I was single in the Sixties.
"I'm happily married now and never once been unfaithful, so I'll never top William."
The former Radio 1 breakfast show presenter went on to say that the Beatles do not measure up to today's chart stars - because they did not dance on stage.
Blackburn, 69, told the Radio Times: "the Beatles and the (Rolling) Stones just stood there with guitars and sang. These days people like Rihanna can sing, dance and do everything."
"I actually think today's artists are better than those of yesteryear," he told the magazine.
Blackburn also said that he had been told he had a royal fan, in the form of the Prince of Wales.
"I'm reliably informed that Prince Charles always listened when I was on Radio London," he said.
