A few weeks ago, we brought you news of Beyonce's alleged forthcoming album and short film project, known unofficially as 'Project Lemonade'.

The star had been dropping plenty of hits about the project over the last while, but had not confirmed anything about it - until now.

With her world tour kicking off at the end of May before swinging around by Dublin's Croke Park in July, a full trailer for 'Lemonade' has made its way online.

The full shebang will air as a 'world premiere event' on HBO this coming Saturday - so it's not yet clear if it is a short film as rumoured, or a TV series, a music video, or something else entirely.

Until then, watch the minute-long trailer for 'Lemonade' below:
