Beyonce Grammy Performance - P 2014

The singer stunned during her opening performance of "Drunk in Love" with husband, Jay Z. This is what she wore.

Similar to Beyonce's style in the "Drunk in Love" music video, the superstar channeled a sultry, sexy vibe for her opening Grammys performance with her husband and rap star Jay Z.

The superstar opened the music awards show dressed in sheer black tights which appeared to be embellished with rhinestones. We were curious as to where those tights were from -- and as it turned out, the tights were, in fact, from Saint Laurent's fall 2013 collection. (Kate Moss also was spotted wearing these beauties after their debut on the runway last March.)

After we reached out via email, a rep for Beyonce's stylist, Ty Hunter, also told us the designers behind Bey's hot outfit -- she wore a custom bra, La Perla collar, Nichole de Carle bodysuit, Stuart Weitzman heels and Jennifer Fisher earrings.

Queen B can do no wrong on stage, ever.
