Beyoncé has released an extended trailer for her upcoming 'Lemonade' project.

The singer recently debuted a 20-second clip for the mysterious enterprise.

A full-length one minute trailer has now been uploaded to YouTube.

It features the US star asking questions like 'What are you hiding?', 'Why can’t you see me?' and 'What am I doing, my love?'.

The project is set to be unveiled HBO in the US on Saturday (April 23).

The mystery surrounding 'Lemonade' has increased speculation that Beyoncé could be about to release a new album.
