Denise Richards And Richie Sambora Call It Quits Again

Talk about on again, off again! Richie Sambora and Denise Richards have broken up once again! According to sources, the couple had an epic argument in Nashville and Denise pulled the plug on the recently revived relationship. Apparently the blow-up happened last week before the CMT Awards, where Richards was supposed to be Sambora's date on the red carpet before he bailed on the appearance!
