Grammys Collab: Kanye, Rihanna, Paul McCartney Unite on ‘FourFiveSeconds’

Kanye West, Rihanna, Paul McCartney Debut 'FourFiveSeconds' Live at Grammys (Rolling Stone)

The powerhouse ensemble of Rihanna, Kanye West and Paul McCartney dazzled with their pop collaboration "FourFiveSeconds" in a relatively stripped-back performance at the Grammys. The former Beatle passionately strummed the tune's propulsive riff, as the singer and rapper sang their verses, joining in on the choruses. The majority of the performance took place in front of a white-light backdrop, until it lifted up to reveal dark curtains. West and Rihanna faced one another toward the end of the song, leading a clap-along with Kim Kardashian and Jay Z joining in.
