Beyonce -- Drops Surprise Video ... Featuring Blue Ivy!!!

Beyonce just did what Beyonce does best ... shocking the world with a surprise new single and music video co-starring Blue Ivy, and the timing is obvious.

Queen Bey released "Formation," a Louisiana-themed video exclusively on Tidal Saturday -- just a day before her Super Bowl halftime performance with Coldplay ... fans are going nuts.

Blue steals the show midway through the video, popping a little dance move in the process.

It's good to be Beyonce.
