The Bay Area rapper took part in our mock game show, and even impressed herself with how much she knew about past VMA performances.
She stumbled a bit over the first question — Who closed last year's Video Music Awards? — guessing David Bowie, Eminem and Birdman before coming up with the correct answer: a red-suit-wearing Kanye West.
She also scored correct guesses when she answered which song Britney Spears sang in her debut Video Music Awards performance ("... Baby One More Time") and what Madonna song Katy Perry sang ("Like a Virgin") when she fronted the house band one year.
Sounds like she'll do just fine come Sunday night, when she works the black carpet as a host for MTV.com. Others who've filled this role in past years include Coco Rocha, Christian Siriano and Adrienne Bailon.
"I'm super excited to be the red-carpet host at this year's VMAs," Kreayshawn said. "I can harass celebrities about what they're wearing, what they ate before they got to the carpet, all sorts of funny stuff."
The 21-year-old was featured on Saturday's (August 27) new episode of "When I Was 17" with other VMA Best New Artist nominees Big Sean and Tyler, the Creator.
The 28th annual MTV Video Music Awards will air live Sunday from Los Angeles at 9 p.m. ET/PT, following the Selena Gomez-hosted pre-show at 8. See the list of nominees, revisit last year's highlights and vote for Best New Artist by visiting VMA.MTV.com.
