Beyonce proved exactly why she's Queen B as she took to the stage at Sunday's Super Bowl.
The mother-of-one, who was rejoined by her Destiny's Child bandmates Kelly Rowland and Michelle Williams for a rendition of their greatest hits, showed off her serious style in a sizzling leather lace leotard.
The 31-year-old songstress dazzled fans in the Rubin Singer creation, which featured a plunging neckline cut to her navel and lace appliques at her sides.
Intricate lace panels gave fans a glimpse of the star's toned midriff, while the lace dipped-hemline at the back highlighted her infamous curves.
The star's look for the Super Bowl XLV11 performance in New Orleans was rounded off with fierce leather gloves, knee-high socks and smokey eye make up.
Performing a string of the band's best-loved hits at the half-time show, Bey's on-trend leather lace look stood out from her bandmates - who opted for far simpler leather designs.
Beyonce's decision to use the little-known New York designer shouldn't come as too much of a surprise, as the star has been working with him for about five years.
The pair are said to have a very close working relationship, with Rubin also designing for Beyonce's sister, Solange Knowles.
Ahead of Beyonce's eagerly-awaited performance, the designer took to Twitter to share some backstage pictures as he got the star ready.
Revealing a "super style moment" was going on, he tweeted:
In a recent interview, Rubin Singer admitted he knew dressing for the Super Bowl was a huge moment in his career.
He said: "Everyone's expecting Beyonce to go with a major designer.
"She knows it's a game-changed - no pun intended."
