The former Disney star looked seriously sexy in the barely there Calvin Klein dress that boasted a deep v-neck, cut out detail on the sides and a sparkling hem that trailed behind her as she walked.
Selena ditched her bra (eek!) but thankfully managed to avoid any kind of nip slip or other boob-related wardrobe malfunctions as she posed hand-on-hip for the paparazzi.
The Same Old Love songstress flaunted her absolutely i-n-c-r-e-d-i-b-l-e figure (is waist envy even a thing?!) in the pillar-style dress but it was her bouncy, gravity-defying waves that really stole the show...
Selena - who is famed for her sleek, svelte, straight locks - opted for a TOWIE style blow-dry and a classic side fringe for the evening as she rubbed shoulders with Taylor Swift, Lady Gaga and Ciara. Former flame Justin Bieber was also in attendance.
A fierce pair of hoop earrings and a smokey eye winged out at the corners was all Selena needed to secure a spot at the top of our best dressed list.
