R&B superstar Chris Brown has revealed details of his forthcoming new single, 'They Don't Know', and has announced that it is a part of his "unity campaign". 

The campaign, as explained by Brown on his official Twitter page in the early hours of this morning (June 14), will "encourage all races, genders, sexes, (everyone) gay or straight to love each other!"

'They Don't Know' also features vocals from the late Aaliyah and Brown returned to the social networking site again today to add that he feels it's important to be a good role model and use his fame to help others: 

"As a young inspiration to all types of people around the world, I have a moral obligation to let go of grudges or bs."

The artwork for the song can be seen below and the 'Don't Wake Me Up' hitmaker confirmed that the "single and video will definitely drop MONDAY", which is June 17.
