Backed by the studio track, Gaga tackles the dance moves by Parris Goebel with ease, opening the performance dressed in a black latex bodysuit and wearing a white cape as she dances through her crew of dancers, before being joined by ballroom icon Honey Balenciaga early in the video.

As for how that all happened, Gaga has pulled back the curtain some in a new behind-the-scenes video.

Grammys broadcast; Gaga was in attendance as a nominee (and eventual winner) for the Bruno Mars duet “Die With a Smile.” That song has an earnest, dutiful quality; one senses both performers straining to produce a wedding-song standard.
