It's a night where the biggest names in music takes their tunes to Sin City.
And
there was no shortage of glamour as the stars stepped on the blue
carpet at the 2013 Billboard Music Awards in Las Vegas, Nevada on Sunday
night.
Jennifer Lopez was an early stand out as she led the trend on sparkles in a very low cut gold gown.

The Waiting For Tonight singer beamed as she stepped out on the arm of her new toyboy Casper Smart, flaunting her curvy figure in the mermaid-themed ensemble.
The mother-of-two left no patch of skin unseen as the sheer skirt put her well-toned pins front and centre.
And the American Idol judge kept to her bejewelled theme, matching her ensemble with gold Christian Louboutin heels and a similarly hued square clutch.

Also
joining in on the trend -- and sure to make the best dressed list --
was country-turned-pop crooner Taylor Swift in a shimmering blue mini
dress with perfectly placed sheer cut outs.
The 23-year-old returned to her simple Southern roots for her attire, sticking to a high neckline and high hemline that complimented her slim figure.
Kelly
Rowland added her name to the mix in a light-catching white and silver
sequinned gown that revealed much of her smooth legs.

Arriving
early to the scene was Selena Gomez, who made sure she was dressed to
impress as she hit the red carpet at the MGM Grand Hotel.
The 20-year-old pop star flashed plenty of flesh in a revealing white futuristic-style gown, which was slashed to the thigh and featured multi-coloured neon trim.
The dress in question displayed Selena's very slim and toned figure and the pink, green and yellow accents around the neck and arms made it fashion forward.

However, as Selena turned around, the gown failed to flatter her figure, with it's ill fit at the back and odd sheer nude panelling.
The Come & Get It star paired the attire with some silver strappy heels and wore no other accessories, bar some stud earrings and a ring on her finger.
She accentuated the pink in the trim further by wearing lashings of pink lipstick on her pout and had heavy black wing tipped eyeliner around her eyes.
She had also straightened her hair, pulling it back into a messy ponytail, but despite it being a sleek style, her tresses at the back appeared matted and frizzy.
Selena is set to be sitting next to Bieber at the Billboard Awards on Sunday night.
The Baby hitmaker and the gorgeous brunette singer appear to have patched things up since their split in the New Year and are expected to go public at the annual music awards in Las Vegas on Sunday night.

According to Us Weekly, a source has revealed Selena, 20, will be sitting on the front row at the MGM Grand Garden Arena right next to Justin, with her close friend Taylor Swift on her other side.
The insider said it was 'clearly no accident', adding, 'Their camps must have requested this seating arrangement. No way would it have happened without their go-ahead.'
Rumours have been circulating the pair are back together since they were caught kissing backstage in Norway, and were then seen cuddling in a picture uploaded to Instagram by Justin last month before he deleted it.
