Eminem gave Pink his stamp of approval by asking her to lend her vocals to “Won’t Back Down” off his platinum album Recovery, but what does pop’s edgy star think of Marshall Mathers?

“I think he’s one of the most poetic, ballsy, and hilarious people this industry has ever seen,” Pink told SPIN magazine.

Unlike her pop peers Britney Spears, Christina Aguilera, and Jessica Simpson, Pink was spared Em’s wrath in his songs. “I was always afraid he’d pick me as a target, but he’s always been nice to me and finally approached me to be on the album, so I must have done something right,” said the flattered singer.

Eminem expressed his admiration for his fellow rebel in a previous interview. “I’ve always respected what she does,” he told BBC Radio 1. “When we did the track, I heard her on it and knew vocally she’d smash it.”

The duo’s rap-rock collabo can be heard in the commercial for Activision’s Call of Duty: Black Ops. Eminem has also been performing the song, sans Pink, at his live shows.
