Rihanna has reconnected with Chris Brown on twitter

The 'S&M' singer added her ex-boyfriend to the list of people she follows on the micro-blogging website and he has added her in return.

Twitter followers of the pop star expressed concern she had made contact with the 'Kiss Kiss' singer - who two years ago attacked her leaving her with a split lip and cuts and bruises to her face - and openly speculated as to whether the stars had rekindled their romance.

After one fan asked if she was back with her former boyfriend Rihanna snapped: "its fu**in twitter, not the altar! (sic)"

After the admirer became upset she quickly apologised, explaining that she wanted to make it clear to all her followers that she was not back in a relationship with Chris

She wrote: "babygirl I'm sorry, I didn't mean to hurt or offend u! Just needed to make it clear to the Navy! I still Stan for u xoxo. (sic)"

Chris, 21, was sentenced to five years probation and six months of community service for assaulting Rihanna in February 2009.

Last month, the 23-year-old star revealed she didn't expect to ever talk to him again despite agreeing to have a restraining order against him relaxed so he could more easily carry on with his career.

The 'Rude Boy' singer explained: "We don't have to talk again ever in my life. I just didn't want to make it more difficult for him professionally.

"What he did to me was a personal thing. It had nothing to do with his career. Saying he has to be a hundred feet away from me, he can't perform at awards shows, that definitely made it difficult for him. That was the only thing it was going to change, so I didn't care."
