Rihanna Avoids Polar Vortex By Going Topless And Paddleboarding In Brazil

Singer posts latest string of sexy bikini pics, making us all jealous.

The weather outside where you are might be frightful, but Rihanna has the perfect antidote to the latest polar vortex: topless bikini pics. Yeah, that's kind of her go-to move, but as much of the U.S. shivers through the latest single-digit arctic blast, Rih Rih has headed south to Brazil to chill in the ocean on her surfboard and soak up the sun.

Here are the hottest pictures from her Copacabana Beach escapade, which were taken during a photo shoot for Vogue Brazil:

The over-the-shoulder, "oops, I forgot my top" yacht picture.

For real, this ride is strictly tops-optional.

A smoldering sunset snap.

Girls just wanna have fun.

Taking it to the water for some deep sea paddle boarding.

What's exercise without a little smoke break?

"Did you say tiger shark or time for lunch?"

She wasn't going to post this one, but she figured, "my smile made this a tad less than 'the most' lol."

End of an exhausting day, taking a break in the boat and listening to some tunes.
