Dang, J. Lo!

During a performance of her song 'Booty,' Jennifer -- or should we say her most famous asset! -- stole the night at 'Fashion Rocks,' an annual international charity fundraiser, this year held at the Barclays Center in Brooklyn, New York.

The 45-year-old triple-threat sizzled as she unashamedly bared her back side as she stormed the stage.

Clad in a sequined minidress, Jenny From the Block's appearance had many a fan wondering if she is in fact aging backwards.

The 'Booty' singer was in great company, performing among Luke Bryan, The Band Perry, Nicki Minaj, Rita Ora, Pitbull, Usher, KISS and Afrojack at the Fashion Week fest, which was hosted by Ryan Seacrest.

The concert (televised on CBS, 9/8c) celebrates the relationship between music and fashion.

In case you missed it, Justin Bieber had his own 'Fashion Rocks' moment. While on stage with model Lara Stone introducing Rita Ora, he responded to booing -- a spectacle seemingly staged -- by stripping down to his 'Calvins' while all his Beliebers at home stared at their TVs in disbelief.
