Selena Gomez's Cutout Dress Is Sure To Get Justin Bieber's Attention

Well, that's one way to get Justin Bieber's attention!

Selena Gomez attended the 2014 iHeartRadio Music Awards in L.A. on Thursday wearing a hear-turning frock that left little to the imagination.

The 21-year-old stunner sported a tummy-baring burgundy crop top and matching flared skirt by Cushnie et Ochs. The highlight of the top? A revealing keyhole cutout that took the outfit from classy to flashy.

Rather than take attention away from the stunning look with bright makeup, the "Spring Breakers" actress opted for a neutral look, with nude lips, bronze skin and a hint of mascara.

Clearly delighted with her gorgeous look (oh, to be hot, young and famous), Selena posted a pouty Instagram selfie en route to the event.

But did the Biebs notice his ex? We don't know but on the same day, the Canadian pop star posted an Instagram pic of himself and Selena's rival Ariana Grande in the studio together.

Oh well, maybe Orlando Bloom appreciated her efforts!
