Wiz Khalifa , Bruno Mars , B.o.B Cover ‘ VIBE’

On the cover of next month' s VIBE magazine are Bruno Mars , B . o . B

. and Wiz Khalifa — we ' re assuming that' s the reason the colors

this issue simply had to be " Black And Yellow ". Considering this is

the Rolling Papers rapper ' s first cover for the music mag , we have

to wonder , why the long face ? Was this photo taken just moments

after his beloved the Steelers lost the Super Bowl ? In fact , neither

Grammy nominees bookending him in the photo look too happy either ,

considering they ' re being touted as "The New Pop Music ". Lighten up

boys!
