One Direction's Harry Styles and Liam Payne

The One Direction boys are ambassadors for cancer charity Trekstock and are helping the organization raise money by selling off a hot date with themselves during a weekend in London.

According to The Sun newspaper, Harry said: "A lucky winner and a friend will win a five-star weekend in London's Carnaby Street. You will be given some spending money to go shopping, you will be flown into London, then me and Liam will be taking you out for the evening."

To enter the competition you can bid at, however, you must be over 13 years old to go on the date.

Trekstock - officially launched in March 2010 - supports young people with cancer and they aim to help beat the disease through funding research and ensuring people have the relevant information to make better lifestyle choices.

They are working with Cancer Research UK scientists to help prevent, diagnose, treat, and ultimately beat cancer.
