The 'Problem' singer was spotted strutting her stuff down the red carpet at the Los Angeles event rocking a very racy ensemble...
Turning more than a few heads as she posed for the cameras, Ariana ramped up the va-va-voom in a tiny strapless dress by Moschino.
Her raunchy frock featured a high hemline, exposed gold zip details and pockets, plus an in-built belt with the designer's name spelt out across the front.
As if her teeny tiny dress wasn't attention-grabbing enough, Ariana then took things one step further by adding a smouldering pair of over-the-knee boots.
Designed by Tom Ford, her daring footwear added inches to her petite frame while making a pretty major style statement.
She did add a (slight) girly touch to her look by painting her nails a sugary pink hue, whipping her brunette locks into a high ponytail before lacquering her pout with bold rouge lippy.
But this wasn't the only outfit Ariana rocked that evening - the starlet made a few costume changes as she later took to the stage not once, but twice.
Ariana joined Jessie J and Nicki Minaj to open the ceremony with their new track 'Bang Bang', and also treated the audience to a performance of her single 'Break Free'.
And that's not all - the singer managed to scoop the gong for Best Pop Video for her tune 'Problem', before releasing her new album, My Everything, straight after the show.
There's no stopping this girl!
