Katy Perry may be nervous about hosting the 2017 MTV Video Music Awards tonight (August 27), but she sure didn't look it when she stepped onto the high-tech blue carpet.

Wearing a crisp white mermaid gown, the "Swish Swish" singer really went for the Hollywood glam with this one. And although some might think it's a little too conservative for the no holds barred awards ceremony, the look made Katy stand out amid the sea of skin-bearing and super casual outfits that we usually see at the VMAs.

Along with hosting duties, she'll also be performing her new single and announced at the pre-show that Nicki Minaj will be joining her onstage. Be sure to tune in for that one.
