Currently promoting "Katy Perry: Part of Me 3D" in Brazil, Katy Perry striked her best diva pose on the pink carpet for the Rio de Janeiro premiere.

The singer donned a glamorous silver Dolce & Gabbana floral lace gown with long sleeves and a long train which was accented with a silver embellished belt.

A bit of edge was provided via her super sleek bun, burgundy lipstick and dark smokey eyes.

A pair of diamond stud earrings and multiple silver rings added an extra sparkle.

Before the premiere, Katy started off the day with a photocall in Rio de Janeiro, sporting a revealing Versus dress from the Fall 2012 collection.

Her lime green short-sleeved mini dress with diamond cut-outs down the chest was paired with burgundy Brian Atwood pumps with a studded heel.

She kept the rest of the styling simple with her back to black hair in a side-parted straight bob cut, glossy lips and a crucifix ring.

Love the hair and the shoe choice but it is too much cleavage baring...
