NO wonder his pants are low and his shirts are off Reports are circulating that Justin Bieber is said to ditch his pretty-boy pop persona and morph into, yes, a rapper.

(Given he’s been hanging out with Jay Z, Will Smith and Pharrell Williams, we should not be surprised.)

Biebs recently tweeted, “Fun night in the studio with big bro @Pharrell.” While Pharrell Williams has produced albums for artists spanning several genres, he’s one of several major hip-hop players the Biebs has recorded with in recent weeks.

Bieber recently posted an Instagram photo of himself with rapper Future and the caption, “In the studio making a smash with my bro @future.”

A few weeks ago in Detroit, the Biebs even tried his tongue at rap by covering the Eminem tune Lose Yourself (he stuffed up the lyrics, but hey, he gave it a go).

Some, however, are not convinced. Sharon Osbourne weighed in, saying, Biebs “doesn’t realise he’s white and not black; that’s a huge problem.”
