Eminem felt Pink and Rihanna were the perfect addition to his new album.

The 'Just Lose It' rapper - who famously collaborated with Dido in the 2000 hit 'Stan' - reveals the female singers were the only people who could "pull off" his tracks.

He said: "When I did the song that I did with Pink I laid my parts first and kind of heard her on the record. I felt like she would smash this record, so I gave her a call and she was with it, so we did it.

"The other that I did with Rihanna is one of those tracks that I felt only she could pull it off."

The hip-hop star - who has parodied the likes of Madonna, Britney Spears and Mariah Carey throughout his career - explained his new album 'Recovery' will make sense once fans hear it.

He told Skyrock FM: "Both of the records, I guess you just got to hear them to know what they are."

Eminem went on to praise relative newcomer to the hip-hop world Lil Wayne, who he collaborated with on the 'Drop the World' track and Drake's 'Forever' single.

He said: "I've always respected what Wayne does. Wayne to me is one of the greatest in The Game right now."
