One of our favorite moments of the 2015 Grammy Awards? Oh, just Rihanna, Kanye West and Paul McCartney absolutely slaying their performance of 'FourFiveSeconds.'

While their kickass (albeit random) collaboration alone was epic enough, the fact that they totally freaking killed it just makes the performance that much better. As the iconic Sir Paul McCartney completely shredded it on the guitar and Kanye spit all the rhymes, Rihanna belted. it. out, proving to the world why we should all pray at the altar of Bad Gal RiRi and those insane pipes of hers. Girl can sing! (While we obviously knew that already, an insane live performance such as this is always a helpful reminder.)

What did you think of Rihanna, Kanye West and Paul McCartney's killer performance of 'FourFiveSeconds'? (In case you couldn't tell, we loved it!)
