Katy Perry
might have had the best outfit of the night!

The "Roar" singer hit the red carpet for the 2014 MTV Video Music Awards in Los Angeles on Sunday, rocking an all-denim dress, matching her date Riff Raff in his denim suit.

Perry said that her look was a throwback to Justin Timberlake and Britney Spears, who rocked the same denim-on-denim look at the 2001 American Music Awards.

The 29-year-old also posted a photo of them holding hands via Instagram before hitting the red carpet.

"About to roll thro... Look for us in da lambo #THISISHOWWEDOVMAS," she captioned the candid snap.

The rapper recently remixed Perry's "This Is How We Do" single, and confessed his love for the brunette beauty earlier this year.

While we're not sure if they are actually dating, they would be a pretty interesting couple! What do you think about Katy and Riff Raff's matching outfits?
