Rihanna offer Chris Brown twitter olive branch

Pop star Rihanna has become a follower of Chris Brown on twitter and he has in turn decided to follow her on the micro-blogging site, signalling a thawing in their relationship. Until recently, Brown had a restraining order preventing him from being within 30m of the "S&M" star, following an incident two years ago in which he assaulted Rihanna, his then-girlfriend.
