Best of all it's so easy to win...simply head on over and Like our new website's Facebook Page, Swimwear Shack.
As long as you are a fan of that page you're in with a chance at winning. We'll pick the 2 lucky winners at random at 4pm tomorrow afternoon.
Tickets can then be collected from Adreno anytime before the event.
Even if you're not in Brisbane or aren't interested in Katy Perry, still take the time to Like our page and help show your support.
