Rihanna announced the release of her new single, which includes Paul McCartney and Kanye West.

The famous singer announced it to her 39 million Twitter followers on Twitter, on Saturday.

Rihanna, who hadn’t released a new song in two years, releases “Four Five Seconds”, in which McCartney plays the guitar while Kanye West raps.

This isn’t the first time that West and McCartney are working together. The two had collaborated last year on West’s “Only One” which was dedicated to his daughter, North West.
