The popstar released the new track Thursday evening, tweeting the surprise to her 42.7 million followers.
Along with it was an artwork cover, showing Rihanna posing braless in a leather jacket. Sporting some flamboyant drop earrings and rocking some serious eyebrows, RiRi captioned the snap: "RihannaNOW.com #R8 #BBHMM #March26."
The caption has left many wondering if an album release is imminent.
At the moment, the only way fans can hear 'B**ch Better Have My Money' is to download the Dubsmash video messaging app.
Riding high on the success of 'FourFiveSeconds' with Kanye West and Paul McCartney, RiRi has been teasing new music for the past month.
Earlier this month, the star said of her new album: "I wanted songs that I could perform in 15 years; I wanted an album that I could perform in 15 years. Not any songs that were burnt out. I find that when I get on stage now, I don't want to perform a lot of my songs. They don't feel like me. So I want to make songs that are timeless."
