The pop star exercises regularly and she likes to work out to contrasting musical styles - high energy dance music to encourage her to go faster, and classical tracks to distract her.

She said: "I either run to something really kind of heavy like some drum and bass or something, or something really chilled something that engages my brain so I concentrate.

"I think that in classical music there's lots of kind of complex things that makes you - well, you get distracted by so many things going on that by the time you think, 'That was amazing, that was really good,' you've kind of done a mile or so."

The 'Starry Eyed' hitmaker is serious about keeping fit and has previously revealed running gives her a huge buzz.

She said: "The thrill of running is purely physical. I could tell you it's a spiritual high but that would be a lie. I'm an endorphin addict. I love the idea of my body being how it should be - in shape and active, able to deliver. The more I train and see muscle definition, the more inspired I am to push myself harder."
