On the day Chris Brown took to YouTube to say he's “not a monster,” a photographer sued the R&B singer, saying Brown's bodyguards beat him as he tried to take pictures at a gym. Robert Rosen sued Brown and LA Fitness International, claiming he was assaulted by a bodyguard after snapping pictures in a gym in Universal City. Brown has pleaded not guilty in that case, which is scheduled for a hearing Thursday. The lawsuit was filed on the same day Brown, 20, defended himself in a video posted on YouTube. Brown is shown leaning in and speaking directly into the camera, which appears to be positioned in front of a bowling lane. He talks about his new album called “Graffiti,” and a single expected this summer. Then he says: “Everybody that's haters, they just been haters. All my real fans, I love you. I ain't a monster.”
