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. The hot actress had told him that she could not continue with the relationship anymore.

The fight reportedly took place at The Hermitage Hotel in downtown Nashville. The 52-year-old rocker was heard "screaming obscenities at the top of his lungs" in the hotel.
The pair's relationship seemed to have come under strain after Denise Richards' ongoing close relationship with her ex-husband Charlie Sheen, a source told Celebuzz. Sheen and Richards have two children together.
Sambora was married to actress Heather Locklear for 12 years before breaking it off in 2006, citing irreconcilable differences. They have a14-year-old daughter, Ava.
Sambora and Richards initially met after both had broken it off with their former spouses. They split in 2007, before reuniting last year.
