Eminem is a diva, he refused to attend the Oscars because he didnt get nominated for best actor for 8 mile, he won the oscar for lose yourself but refused to perform it live, so they had to completely change the musical format that year.
I heard He also pulled out of the movie Southpaw he was supposed to play the lead but he didn't want to bulk up because he felt it would make him age.
Eminem also doesnt like to go in the sunlight much anymore because he feels it will cause him to age faster dude probabaly drinks blood thinking it will make him youthful
