Katy Perry Reveals Killer Cleavage and Her Glam Side in Brazil—Which Look Do You Prefer?

Katy Perry sure knows how to work a red carpet in Brazil, and with two looks in one day no less!

There are many parts of Katy Perry, and during her recent trip to Rio de Janeiro we got a peek at quite a few of them. Or, well, OK—two of them. Right at chest level.

Check out the busty number the "Part of Me" singer wore to promote her film in Brazil. The frock didn't last long, but not because it burst at the seams.

The dress we refer to is, of course, that yellow-green Versus frock. Katy wore it to a daytime photo call for her concert film and, thanks to those strategically placed cut-outs, it gave us about as much of a 3-D view as the movie does.

Extra round of applause for whoever decided to pair the dress with those unexpected, but perfect, red Brian Atwood heels. Like we said, though, the dress didn't last long.

A few hours later, the newly-single singer emerged for an evening premiere in top-to-toe glam. Katy swept her bob back in a sleek updo and rocked a full-length Dolce & Gabbana gown with matching diamond accents.

Which "part" of Katy do you prefer: Bra-less daytime Katy or evening glam Katy? Tell us in comments!
