Though only a few seconds long, Beyonce's latest vid with Blue Ivy is the best thing we've seen on Instagram in a long time. The clip shows Bey and baby Blue flossing, literally, with matching floss picks and matching stunna shades to boot. And during this priceless moment, a new song plays in the background--a beat that bumps along with a sample of a woman repeating "flossin"--and that certainly sounds like Daddy in the background with the ad-libs.

If the snippet sounds familiar, you may have heard a very similar beat on that Jay Z & Timbaland song that hit YouTube in late 2013. No word yet where this song will end up, though we hope a Jay & Bey album is in the works. 

Take a listen below, and let us know what you think of the early snippet.
