Could Rihanna and Chris Brown be warming up to each other again? Celeb blog MediaTakeOut.com seems to think so. The gossip website on Sunday posted screengrabs of both the pop star\'s twitter pages which showed them following each other. The website also added that it had a ‘rock solid snitch\' who confirmed the ex-lovers then went on to exchange private messages with each other. What they said to each other, is not known. It was Rihanna who initiated the contact and Brown immediately reciprocated. One of pop world\'s hottest couples when they started dating in 2007, the relationship soon turned into a circus after Rihanna\'s mangled face appeared on the internet in 2009. Brown, who admitted to assaulting her, was later charged for violence and abuse. After suffering a career setback and serving time for community service, Brown is steadily building his fanbase back, with his latest album F.A.M.E. debuting at number one on the Billboard albums charts. Meanwhile Rihanna\'s album, Loud, has been a runaway success. A song, S&M, from the album has been mired in controversy for its overt and violent sexual content.from gulfnews .
