Actress Parker Posey has blamed Ryan Adams' "personal demons" on the breakdown of their relationship. The SUPERMAN RETURNS star split from the singer/songwriter last year (05). Ryan has also dated Winona Ryder, Alanis Morissette and Beth Orton. And while Parker remains a huge fan of his music, she insists his troubled personality meant their relationship was hard work. She tells the PageSix.com, "He is a really talented musician, but he has a lot of personal demons."
