While Eminem raps about his "Monster" haunting him, Rihanna embraces hers. The singer flexes her vocal skills on the hook to Em's latest: "I'm friends with the monster that's under my bed/ Get along with the voices inside of my head/ You're trying to save me/ Stop holding your breath/ And you think I'm crazy/ Yeah, you think I'm crazy/ Well that's not fair."

The duo's chemistry is undeniable. Prior to "The Monster," Rihanna was featured on Eminem's 2010 hit, "Love the Way You Lie" and Em, in turn, appeared on "Part II" of the song ("Love the Way You Lie (Part II)") featured on Rihanna's Loud album.

The standard edition of MMLP2, executive produced by Dr. Dre and Rick Rubin, will also feature Kendrick Lamar, Skylar Grey and fun.'s Nate Ruess. The deluxe edition will feature five extra songs including features by Sia and Jamie N. Commons.

Eminem's "Rap God" single debuted at No. 2 on the Hot R&B/Hip-Hop Songs last week, thanks to 270,000 downloads (according to Nielsen SoundScan) and 1.4 million U.S. streams (according to Nielsen BDS).
