The 'Come & Get It' songstress pulled out all the stops as she smouldered at the Ischia Global Film and Music Festival in Italy, where she picked up the Kids' Global Icon award.
Making sure she stole the limelight on her big night, the starlet looked positively ravishing in a black floor-length gown which was covered in gleaming, sparky gems.
She also revealed more than a hint of flesh in her raunchy ensemble, which boasted a daring deep neckline plus a super-high thigh slit. Oooer!
To accessorise her flashy getup, Selena wore a very delicate body chain which highlighted her cleavage, teamed with hoop earrings and a nude glossy manicure.
Her pins were elongated with pointed black suede courts and she swept her dark locks into a low bun to help flaunt her frock's sexy backless design.
Biebs must be kicking himself after spotting how stunning his ex looked, although he recently sparked rumours of a new romance by posting an Instagram snap with model friend Yovanna Ventura, adding the caption: "Dinner for 2 ;)".
However, just last month speculation of a Selena and Justin reunion emerged after an Instagram video showed the former flames together amid a large group of people.
We just can't keep up with these two...!
