Cheryl Cole broke down during a TV interview as she lifted the lid on her failed marriage and battle with malaria. The pop star told Piers Morgan that her split from England footballer Ashley Cole had left her heartbroken. X Factor judge Cheryl has so far kept a dignified silence regarding her marriage. But the 27-year-old told Piers' ITV1 show Life Stories on Thursday that she was at a loss to explain why the relationship had collapsed. She said: "Looking back on it, I feel numb. We had a great marriage and a fantastic wedding day but I don't know where it went wrong. To this day I still question that." The marriage ran into trouble following a string of lurid allegations surrounding Chelsea defender Ashley. The couple were officially divorced last month. Earlier this year the singer was struck down with potentially deadly malaria, which she contracted during a trip to Tanzania. Cheryl told the show that she felt so ill as a result of the disease that she thought she was going to die, saying: "It was touch and go for 24 hours. It was serious. I actually thought I was going to die. All I thought was that if I was going to die, please let it be soon." *Cheryl's Life Stories will screen on October 23.
