Singer Chris Brown has fans buzzing with his new twitter messages posted within the last day. In two posts (which have since been taken down), he wrote, "sorry yall, just one of those days' and linked to a You Tube video with pictures of him and Rihanna in happier days with the lyrics to 'Changed Man' playing.

Then his second post said, '"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."
