Cheryl has opened up on what she has called the "worst relationship" of her life.

Speaking to The Sun, Cheryl said that her new track 'Craziest Things' was written about a relationship she was in when she was 16.

The newspaper reports she dated a drug addict for a couple of years whilst living in Newcastle.

Cheryl said that she was "depressed and poorly" whilst in the relationship and looked to escape it for the sake of her health. She said:

"I was in the worst relationship of my life. 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."
