Eminem hosted a Twitter Q&A this afternoon to promote "Southpaw," which premieres today. He took 13 questions from fans who submitted queries via the hashtag #DearSlim.

Eminem, who was originally slated to star in the film, said he turned down the role because his nose is "already fucked up enough." Among other things, he also discussed who he considered to be the boxing G.O.A.T., compared Southpaw soundtrack single "Phenomenal" to the immortal 8 Mile track "Lose Yourself," and commented on the whereabouts of mysterious and loathsome Em character Ken Kaniff.
