Eminem has used a new song to apologize to Rihanna for "siding" with her ex-boyfriend Chris Brown, who assaulted her in 2009.

Axar.az reports that Eminem raps on his track Zeus: "And wholeheartedly apologies Rihanna for that song that leaked / I'm sorry, Rih, it wasn't meant to cause you grief."

He was referring to a decade-old song that leaked in 2019, on which he said "of course I side with Chris Brown". Zeus appears on Eminem's surprise album Music to be Murdered By Side B. The album, which accompanies January's Music to be Murdered By, was released on Friday.

At the time the track leaked last year, Eminem's spokesperson said: "This is a leak of something that's over 10 years old. After Eminem recorded it, he scrapped it, and rewrote it."
