Rita Ora belted out a stellar rendition of the Oscar-nominated song "Grateful" at the 2015 Oscars tonight (Feb. 22), looking absolutely radiant while doing so.

Donning a stunning black and white dress and cropped platinum hair, the British singer delivered a killer performance of the Beyond the Lights tune, pouring her heart and soul into the number and flaunting her insane vocals like there was no freaking tomorrow. In case there was any doubt that Rita Ora could sing -- and having watched her perform "I Will Never Let You Down" acoustic at PopCrush, we didn't exactly have any -- the British powerhouse certainly silenced all of the haters just by opening her mouth tonight. Talk about a performance!

And in addition to her flawless performance, Rita Ora also slayed the fashion game as well. Just in case we were too busy staring at that killer gown, we caught a glimpse of that sparkler around her neck -- a silver, blinged-out snake necklace that was pretty much the most badass piece of jewelry we have ever seen. Considering that snakes are so in right now -- just as Nicki Minaj or Jennifer Lawrence can attest -- we love that Rita Ora used the powerful reptile as part of her ensemble. It was elegant (who could say no to a glinting necklace like that?) with just the perfect amount of edginess to make it totally kickass, too. Obsessed.
