Denise Richards and Richie Sambora have reportedly ended their on-again, off-again relationship.
The pair rekindled their romance earlier this year following a prior romance between 2006 and 2007.
But Celebuzz claims that just before their scheduled appearance at the CMT Music Awards last week, Denise and the Bon Jovi rocker had a huge fight.
'It's over,' an insider told the site. 'They had an epic argument in Nashville and Denise told Richie she couldn't continue the relationship any longer.'
The 52-year-old had been due to present onstage during the awards show but mysteriously cancelled at the last minute.
A source said that Richie claimed to have an issue with his 14-year-old Ava back in LA but later said he was ill.
Denise and Richie first got together after he split from Heather Locklear and she had just ended her marriage to Charlie Sheen.
