Katy Perry and Riff Raff Pull a Britney and Justin in Denim-On-Denim

In a clear homage to Britney Spears and Justin Timberlake's matching denim-on-denim outfit at the 2001 American Music Awards, Katy Perry and Riff Raff showed up fashionably last to the VMAs in their own matching denim-on-denim outfits.

Riff Raff was there to promote his new remix of Katy's song "This Is How We Do." Okay guys. We're talking about you now.
