Eminem says there's a reason he recruited Rihanna to sing on his new single "The Monster" -- people think they're both a little cuckoo. Em tells MTV, "I thought it would be a good idea to have her on it because I think people look at us like we're both a little nuts. 

Nonetheless, Slim says RiRi is the consummate pro in the studio. Even though he sent her the track at the last minute, Em says she still knocked it out of the park. "I sent it to her, she laid the hook, sent it back. She smashed it like she does always. It's pretty incredible."

MY 2 CENTS:

  • People might think Rihanna is wild, but not crazy. 
  • If you were to pick a collab between two truly crazy artists, what would it be?
  • The success of "Love the Way You Lie" probably had a little something to do with it, too.
