Selena Gomez turned up the volume of the 2013 Billboard Music Awards at the MGM Grand Garden Arena in Las Vegas, Nevada before the performances even started.

After taking a break from Atelier Versace, which she flaunted a good many times earlier this year, the singer-actress went back to the rock-star design house tonight, donning a look from the Spring 2013 collection.

The slit-to-there white gown, ripped through with peek-a-boo illusion paneling, had sexiness in spades. (Perhaps she had a certain Billboard boy—cough, Justin Bieber, cough—in mind.)

But it also packed some fun into its sexy appeal, as it was edged in neon piping that reminded me of glow sticks—couture ones, of course.

Metallic Jimmy Choo ‘Malin’ sandals didn’t bring the same colourful punch as the runway shoe. But, similar to the catwalk model, Selena flaunted smouldering, sooty eyes, which put a darker spin on this Rainbow Brite look and contrasted with her more juvenile bubblegum-pink lippie and messy, long ponytail.

Selena has lately been showing us her all-grown-up sartorial side. Do you like her va-va-voom return to Versace?
