The Same Old Love singer looked sensational in the stunning silver frock that boasted hundreds and hundreds of sequins, pretty cap sleeves and nine retro blooms which trailed down her chest to her hem.
Er, we're just a little bit mesmerised by it...
Former Disney actress Selena looked all grown up in the dazzling pillar dress which drew attention to her absolutely teeny tiny waist and shapely thighs.
As if the sparkling sequins weren't enough, the star held a crystal encrusted boxy clutch bag and flashed a winning smile for the photographers as she posed hand on hip.
Selena channelled her inner Cleopatra when it came to her eye make-up (yep, we totally approve) as she eschewed the pretty golds and dusky pink eye shadows for a swipe of thick, jet black eyeliner across her lids.
The brunette beauty - who schmoozed with Lady Gaga, Oscars winner Leonardo Di Caprio and Caitlyn Jenner to name but a few attendees - offset her look with dead straight hair a la Jennifer Lawrence and a Kardashian-esque centre parting.
SO gorgeous, it's unreal.
