Jay-Z has said he has been impressed by Rihanna's dedication to music following her assault in February by then-boyfriend Chris Brown. "Rihanna is a roller," Jay told The Sun. "She goes in hard. She was ready to come back to work from the off. We were working together and she just said to me, 'Let me know when you want me to show up for the video'. But I looked out for her. We talk to each other and I give her plenty of advice."Meanwhile, Chris Brown has hinted that he wants Rihanna back. Earlier this week the disgraced R&B star posted his new song, Changed Man, on Twitter (sample lyrics - ‘I'm a make it up to you and show the world I'm a changed man. Cause you mean that much to me. I don't wanna be done. I'm doing all that I can and everybody hates Chris. They can never understand. So can we love') before later blogging, "MY HEART IS INCOMPLETE... the part that is complete is my love for fans, career, friends, family...God. But I'm missing someone or something."
