Anne-Marie feels happiest when she's crying

Asked when she's at her happiest, the '2002' hitmaker explained: "When I cry. Not just happy tears - I love the release of emotion.

"I can be an extreme person, so my emotions tend to be heightened and I get really happy, really sad or really angry.

"I feel great when I cry - it's that sense of relief."

The music star also admitted to being particularly annoyed by bad manners.

She told Cosmopolitan magazine: "If I hold a door open for someone and they don't say thank you, I normally just shout 'Thank you!' back at them!"

Despite this, Anne-Marie conceded she's spent too much of her life trying to please other people.

Asked what advice she'd give her teenage self, she replied: "Not everyone will like you and you don't have to care. I spent too much time pleasing others.

"Now I'm much happier and less worried about what people think of me."

Last year, Anne-Marie admitted she used to "slap" make-up on when she was at school because she saw it as her "mask".

She recalled: "I've struggled with anxiety since I was 12. As a kid, I was confident and carefree, but when I hit my teenage years I became really shy and would always worry about people looking at me.

"I wanted to fit in at school so much that I just did what everyone else did.

"Make-up was my mask: sometimes I'd slap so much on that you couldn't tell what my real face looked like. Doing this totally took away my personality and I withdrew into myself."
