This video shows a model peeing in the middle of a catwalk before another girl follows whilst being sick but don't worry it's not the end of the glamorous world of fashion- it's an advert.

The ad is the latest shock tactic from the Know Your Limits campaign started by the government to make us all aware of what alcohol does to us.

It is hoped that seeing how the affects of binge drinking can ruin a glam image will make young adults think seriously about how much they drink on a night out.

Check out the ad below and let us know what you think........
