Chris Brown has publicly apologised for attacking his ex-girlfriend Rihanna. In a two-minute video on his website, the R&B star said he thought it was time that you heard directly from me that I am sorry. He said he was seeking help and wanted to live his life as a role model, saying: I wish I had the chance to live those few moments again. Brown pleaded guilty to assault after he was arrested the night before the Grammy awards in February. In the video, the singer referred to his assault as the incident and said: I am very sad and very ashamed of what I have done. Wearing an orange shirt and apparently reading from a script, he told viewers he has repeatedly apologised to Rihanna. The 20-year-old called what he did inexcusable and asked for forgiveness from his fans. Brown was arrested hours after he fought with his then-girlfriend Rihanna in a rented sports car after a pre-Grammy party in Los Angeles. BBC
