Katy Perry co-hosted the 2012 MuchMusic Video Awards with LMFAO which were held in Toronto, Canada, on Sunday.
The singer arrived on the red carpet in a Wonder Woman-inspired VAWK dress from the Resort 2012 collection.
Her black halter dress featured a gold cut-out bodice attached to a sheer chiffon floor-length skirt.
Going all out with the superhero theme, she rocked a purple wig with blunt bangs.
Black Christian Louboutin pumps and a gold bracelet completed the look.
Love the hair colour on this occasion and this dress suited her personality.
Katy was joined by eight young girls wearing various memorable outfits from her past music videos.
