Jennifer Morrison In Kristian Aadnevik - 2013 Billboard Music Awards

I could barely believe my eyes when I saw Jennifer Morrison take to the ‘blue’ carpet at the 2013 Billboard Music Awards at the MGM Grand Garden Arena in Las Vegas tonight.

The ‘Once Upon a Time’ actress flaunted her toned bod, leaving little to the imagination in a Kristian Aadnevik Fall 2013 sheer corset gown (can we call it a gown?).

Seemingly plucked straight from the boudoir to Billboard, this lingerie-inspired design certainly fits the sexy-siren bill that we knew would be a star of this Vegas show. But I wouldn’t have guessed Jennifer would be wearing it.

What shall we call this see-through moment… Sultry Snow White; Racy Rapunzel; Scandalous Cinderella?

Let’s call it 50 shades of too revealing—especially from the back side. It’s a look better suited for the stage.

Long wavy locks and a hot-pink lip were the standard sexy beauty choices, while minimal jewels and a patent Edie Parker clutch completed the effect—not that anyone was looking at her accessories.

Does this outfit leave you happily-ever-after, or was this dark fairytale a flop?
