They say imitation is the sincerest form of flattery, and Britney Spears is flattered! Katy Perry showed up to Sunday's MTV Video Music Awards wearing a denim dress made by Versace Couture; she was channeling Spears' iconic look from the 28th Annual American Music Awards in 2001.

Perry even recruited rapper Riff Raff to emulate singer Justin Timberlake, Spears' boyfriend at the time. Prior to walking the red carpet and collecting her Moonman trophy, Perry dropped hints about her dress, tweeting, "I must admit my outfit is a result of my love for nostalgia and my tumblr addiction."
