Mandy Moore Was Bad For Ryan Adams' Health?

The rocker blames the break-up – after six months together - on the media attention surrounding the pair, insisting he is "allergic" to cameras.

"I found the entire speculation and subsequent photographs and intrusions terrifying and only wish to live as normal a life as possible, so that I might always remain punk as f**k and sober,” he told OK!

"Unfortunately I am allergic to paparazzi and have found the best antidote to that sort of nonsense is staying behind the guitar and typewriter, staying close to my support group of friends and band mates, and not engaging in activities that prevent me from taking care of myself or others."

But the star insists there are no hard feelings with Moore, describing her as a "genuinely sweet, angelic" person.

He adds, "I am grateful for our friendship and how it allowed us both to grow and learn more."
