Jessica Simpson claims she has been abused. The 'Come on Over' singer made the startling confession in a candid interview, although she refused to go into any further details.

When asked by America's Elle magazine if she had ever been physically abused, the singer said: "I don't want to talk about it, but I have definitely experienced abuse in a way that I would tell people to take their heart and run."

The star revealed all the songs on her forthcoming country album 'Do You Know' - which she worked on with legendary country singer Dolly Parton - are autobiographical.

New track 'Remember That' includes the lyrics: "It doesn't matter how he hurts you, With his hands or with his words, You don't deserve it, It ain't worth it, Take your heart and run." The singer has previously revealed she was viciously bullied while at school, with those responsible even attacking her home.

She said: "I would walk down the school halls and hear people talking about me. Some of them would throw toilet paper at my house or throw eggs at my door. "They would also write things on the sidewalk in permanent marker. They really hated me."
