Rihanna hasn't released a new album since 2012's "Unapologetic."
A different sound than anything the singer has done before, the new song also features singing from Kanye West, and guitar by Paul McCartney.

"Kanye came up with the idea of doing just some real street denim, all-American type look," Rihanna said last week in a behind-the-scenes teaser video. "Denim never goes out of style. It's iconic, just like the f------ Beatles."
The video was shot by photography duo Inez and Vinoodh, a celebrity favorite.
On Tuesday, it was announced the all-star musical trio will perform "FourFiveSeconds" at Sunday's Grammy Awards.
The performance will mark West's return to the Grammy stage after a six-year absence, where he will also be performing a solo song. A 21-time winner, West is nominated for two awards, and Rihanna is up for one.
