The 'Wide Awake' star is in Brazil to launch her 3D concert movie for the country's fans.

Katy Perry premiered her 3D concert movie to fans in Brazil yesterday at a film event in Rio De Janeiro that saw her wow photographers in a full length silver ball gown.

The 'Teenage Dream' star stepped out in a short yellow minidress earlier in the day (30th July) that showed off her slim figure, while promoting her first ever cinema release in the country this week.

Katy's dress featured cutaway panelling revealing some skin and she paired the outfit with red velvet heels and a bob hairstyle at the afternoon photocell.

Earlier in the day Katy was pictured leaning out of her hotel window to greet the hundreds of fans gathered below, with the wind blowing her hair into odd shapes.

"I woke up from my cat nap to the sound of hundreds of brazilian katycats outside my hotel room chanting Katy Eu Te Amo," Katy tweeted on Sunday (29th July), before adding yesterday: "I hear you out there (and all of last night!) I might have some spare passes to the premiere tonight for the most dedicated… #KP3DINBRAZIL."

When Katy returned for the evening premiere of Part Of Me 3D she had changed into an elegant silver ball gown, wearing her hair slicked back while posing for pictures at the red carpet event.

Katy was pictured enjoying a short break in Miami, Florida last week, amid rumours she has started dating singer John Mayer in the wake of her divorce from husband Russell Brand.

Katy Perry has been nominated for four awards at this year's MTV Video Music Awards, due to take place on 4th September.
