Rihanna is about to tour the world for seven days in support of her forthcoming seventh album, Unapologetic, but before she boards that Boeing 777 jet, she's giving her fans a special treat. The pop star has unveiled the tracklist for the effort, just two weeks before it arrives.

Revealing all 15 tracks via a handwritten Instagram photo, RiRi collaborates with some big names and even one that may still come as a shock to others. Eminem, who tapped the singer for his 2010 hit "Love the Way You Lie," appears on "Numb," while Future shows up for "Loveeeeeee Song."

Chris Brown is the crooner who may boggle the minds of some fans who think the on-and-off again lovers should steer clear of one another due to their sordid past. He lends his talents to "Nobodies Business" -- shouldn't there be a grammar check on that title?

Monday (Nov. 5), The BoomBox reported that Emeli Sande penned a track for Unapologetic, though the U.K. songstress has yet to disclose what the title of the effort is in a recent interview.

Unapologetic arrives Nov. 19.
