LOS ANGELES, California (X17online) - A source tells Us Weekly that Chris Brown and Rihanna have a "volatile" relationship, and an insider close to Rihanna tells the magazine that she had "clearly visible" bruises on her neck in early December.

The friend asked the singer what was going on with her and Chris, to which she simply responded, "We broke up again."

According to Life & Style Chris Brown has had a previous encounter with law enforcement.

At a hotel in Miami in 2007, police were called to Chris' room after he got into a fight with his mom and was reportedly "screaming and throwing dishes."

"He was fighting with his mom. Neighboring hotel guests alerted security and they came upstairs to the room, saw the broken dishes and the mess, and then asked his mother to leave the room.

Police were then called, but charges were not filed as Chris simply paid the hotel bill and left the hotel," a source told the magazine.
