Cheryl Cole: Aggressive relationship that inspired new song Craziest Things made me depressed and poorly
Craziest Things - which has the lyrics: 'We say the craziest things like I love you, hate you, don't need you, f*ck you' - is about an ex-boyfriend who Cheryl had a horrible time with in her teens.
'I was in the worst relationship of my life,' Cheryl, 28, tells We Love Pop.
'We swore, we fought, we did everything it says in that song.
'People think it's passionate and fun, but it's aggressive and wrong. I was depressed and poorly.
'I had to end it for my health.'
Cheryl endured the turbulent relationship as a young teenager when she was living on Newcastle's rough Heaton estate.
She recently spoke about how much her life has changed since she won a place in Girls Aloud on Popstars: The Rivals 10 years ago and moved away from the area.
'I've dined with Prince Charles,' Cheryl told The Observer, 'but I've also sat in a crack den, if you like.'
