Peaches Geldof, the daughter of Irish rock star Bob Geldof and Paula Yates, is dead at age 25. "At this stage, the death is being treated as unexplained and sudden," said a statement from Kent police, who discovered her body Monday. The former model and journalist was known for her hard-partying ways, including an alleged history of heroin use. Geldof was married to rock star Thomas Cohen, with whom she has two sons. Her own mother died of a drug overdose when she was 11. "We are beyond pain," her father said. "How is this possible that we will not see her again? How is that bearable?"
