As eMackinations pointed out in a post yesterday, this is ABSOLUTELY Beyonce's homage to Gwen Verdon dancing to Mexican Breakast with choreography by Bob Fosse.
Which became very popular when the video from that song was put to the music of Walk it Out.
There's so much of the 3-person Fosse-style form in this video. Pieces of There's Gotta Be Something Better Than This from Sweet Charity and The Manson Trio from Pippin.
And when you combine that with some KILLER hip-hop moves and a song that makes me do my model walk down the street, I am in heaven!
