Denise Richards and Bon Jovi rocker Richie Sambora broke off their relationship after having a massive argument before the CMT Music Awards last week. According to Celebuzz, the pair had an "epic" argument in Nashville, where Sambora was expected to present one of the awards. However, due to the heated argument, Sambora reportedly cancelled his appearance at the awards and flew back to LA, and Denise Richards was photographed on the red carpet alone.
