The Shake It Up star was pretty in pink as she walked the bright blue carpet at the event, where she was joined by her long-term boyfriend Tristan Klier.
Bella always hits the mark with her evening style and this time her look didn't disappoint as she sauntered along in a super-cute ice cream pink dress designed by Miu Miu.
Her sugary shift dress featured delicate green and blue embroidery with a little daisy adorning the neckline.
The 'Call It Whatever' singer toted a coral clutch in one hand while layering her wrists with heaps of mixed-metal bangles, lacquering her talons a sophisticated pale grey hue.
But our fave part of her look had to be her a-mazing peep-toe shoes! We love the bronze satin finish of her towering footwear, not to mention the dazzling sparkly silver heels!
And in true Bella style she didn't fail to impress on the beauty front, parting her strawberry blonde locks in the middle while styling the lengths in a sleek and smooth blow-dry.
Upping the drama with her make-up, Bella showcased sultry smoky brown eyes, heaps of black eyeliner and a bright glossy red pout.
And congratulations are certainly in order as the starlet managed to scoop the 'You're So Fancy' award at the lavish do.
Well done, Bella!
