Brown, 20, who pleaded guilty to attacking the 'Umbrella" singer in June and was sentenced to five years supervised probation and community service, was also ordered to stay away from her.
He did not give any details about the incident on the advice of his attorney, but earlier this month he released a two-minute video on TMZ.com expressing his “deepest regret" for his actions. But for Rihanna, the video has left her reeling, as it has led to more publicity about the fall-out.
“She"s in total shock. It was like he gave her another blow, albeit one of a different kind," the Daily Express quoted a source as having told Britain"s Now magazine.
“All she knows is that it"s in the news again and that"s the one thing she didn"t want. She"s been trying to put it behind her and move on as fast as possible. They spoke earlier last week and Chris made no mention of any public statement then. She wishes he"d given her at least a heads-up about it. But that"s Chris, always thinking of himself first and forgetting how this would impact on her," the source added.
