When Katy Perry  tweeted the following to Britney Spears  during a conversation about impressions ahead of the MTV VMA Awards, we didn't quite realize how literal she was being.
@britneyspears  I'll show u my best impression on the red carpet at the VMA's tomorrow... Wait for it bb.

Katy pulled off a flawless reinterpretation of Britney's famous denim look from the 2001 American Music Awards, where the pop princess famously coordinated with then-boyfriend Justin Timberlake . The look went down in fashion history as one of the most memorable couples looks of all time, and Katy told fans that the throwback outfit she sported on the red carpet was a "result of my love for nostalgia and my Tumblr addiction."
Katy did have a little help putting this look together, though. While most of us DIY  our costumes, she looked to Versace  for a reworking of the original patchwork strapless gown. She also roped in rapper Riff Raff to play her "Justin" on the red carpet. Do you think this pair did our favorite teen couple justice with their homage, or will there only ever be one Britney and Justin?
