Tove Lo opened up about her ''very brutal break-up'' on her new album.

The 'Cool Girl' hitmaker had no problem emotionally baring all on her LP 'Lady Wood'.

She told NME: ''The relationship was amazing and unreal but then there was a very brutal break-up. But I write about every single piece of it and I appreciate all of it.

''The whole album is about chasing rushes. I love to live like that because it gives me a lot of amazing moments and experiences but I do realise it's probably not a long-term solution to life.''

Meanwhile, the 29-year-old singer previously revealed the title for her album 'Lady Wood' is a reference to a ''female hard-on''.

Asked what the title of her LP means, she explained: ''It's a female hard-on I guess. But it also for me stands for ... you know when you want a girl to be brave, you go, 'Grow some balls?'

''If someone has balls it means someone is brave, outspoken, and whatever characteristic a man has, which is very unfair. And if you think someone is cowardly, you say, 'Don't be a p***y', you know? There isn't really a word for the female equivalent of balls, so I thought this just fits really well.''

And Tove previously opened up about how it took her a year to recover from her vocal chord surgery, which took place in 2014.

She said: ''It took me about a year to build my voice back up ... I feel finally at peace with it now. I'm really happy to feel like I am able to tour.''
