Elsa Hosk believes the Victoria's Secret Fashion Show is ''the most important day'' of her ''entire year''.

The 28-year-old model is set to grace the runway at the lingerie giant's forthcoming catwalk show, which will take place in Paris, France, on December 5, and the star has admitted despite working out like ''athletes'' all year round, when she finally steps foot on the runway it's the ''cherry on top'' and the highlight of her year.

Speaking in a video posted on VictoriasSecret.com, the blonde beauty said: ''The fashion show is definitely one of the most important days of our entire year and even though we train like athletes, pretty much all year, the fashion show is the cherry on top. When I step on the runway I want to know that I did everything I possibly could to earn my place in the fashion show.''

The Swedish beauty has revealed she is a competitive person, and will always give ''100 per cent every time'' she works out.

Speaking about her mentality and fitness regime, she said: ''I've always been the kind of person that competes with myself. When I'm in the gym I give 100 per cent every time, and you definitely can't fake it.''

Although the catwalk icon has admitted she trains hard not to look better and be fitter than fellow models, but so she becomes a better version of herself.

She explained: ''Fitness is not about being better than someone else it's about being better than you used to be.''

Meanwhile, Elsa - who gained her angel wings in 2015 - has admitted she ''never'' thought she would be a Victoria's Secret Angel and has revealed working for the underwear brand has been a ''really surreal'' experience.

Speaking previously, she said: ''When I first started [modelling], I had no idea that I was even going to get one job.

''I never thought I would get to the point where I was walking Victoria's Secret fashion shows and being and Angel. It's all still really surreal to me. So it's such an amazing surprise for me in my career to be able to do this.''
