RIHANNA PERFORMS @ A PRE-SUPER BOWL EVENT IN MIAMI!

Rihanna performed at a pre-Super Bowl event in Miami on Thursday night - too bad half her costume went missing before she stepped on stage.

The Barbados-born beauty - known for her, shall we say daring fashion choices - may have outdone herself with a catsuit that was missing one leg, a sleeve, and part of the torso.

The one-shouldered neckline plunged straight to the singer's waist, revealing a black strapless bra that was part of the ensemble.

The bodysuit's odd white piping made it reminiscent of a sexy Santa Claus suit, only in black.

The outfit was cooked up by stylists Mariel Haenn and Rob Zangardi, the creative minds behind many of Rihanna's costumes and red carpet looks, according to the Daily Mail.

Rihanna took the stage at the Pepsi Super Bowl Fan Jam, where she performed songs from her recent album, "Rated R," including "Russian Roulette" and "Wait Your Turn." She was joined on stage by Timbaland for part of her set.

Last Sunday she appeared at the Grammys along with Jay-Z and his nephew, Julez Smith, as she and Hov accepted the award for best rap/sung collaboration for "Run This Town."

It marked a year since the sultry singer was assaulted by then-boyfriend Chris Brown.

The Super Bowl pre-party continues with another show in Miami on Friday, at which Nelly Furtado and Pitbull are among the anticipated line-up.

Just don't expect another outfit as eyebrow-raising as Rihanna's.
