Denise Richards Splits With Richie Sambora (EXCLUSIVE)

Denise Richards and Richie Sambora have split, Celebuzz has exclusively learned.

The pair decided to end their rekindled romance after an ill-fated trip to Nashville last week, where the Bon Jovi rocker, 52, was scheduled — but failed — to present on stage at the CMT Awards after a monumental blow-up, a source said.

“It’s over,” according to the insider.

“They had an epic argument in Nashville and Denise told Richie she couldn’t continue the relationship any longer.”

The 41-year-old Wild Things actress was scheduled to accompany Sambora — whom she reunited with last November after splitting in 2007, before going their separate ways again in January — to the CMT Awards at the Bridgestone Arena on June 6.

But she ended up walking the red carpet alone after Sambora cancelled his appearance and flew back to Los Angeles before the show even started.

When asked where “better-half” Sambora was, one red carpet source said Richards — who has three daughters, Sam, eight, and seven-year-old Lola, with ex-husband Charlie Sheen, and Eloise, whom she adopted in 2011 — quipped that her makeup artist was filling the role.

One Academy source told Celebuzz that Sambora initially told them he had to go home to take care of a personal problem with his 14-year-old daughter to ex-wife Heather Locklear, Ava, but later told one official that he was sick and needed to leave right away.

According to another source close to the situation, Sambora was unable to move past a jealous streak stemming from Richards’ close friendship with ex-husband Sheen.

Last week, the ex-Two and a Half Men star confessed in an interview to Rolling Stone magazine that he wanted to have sex with Richards again.

“She still looks f**king great,” Sheen, 46, was quoted saying. “Do I want to? Yeah! Does she? Don’t know.”

Sambora and Richards’ relationship-ending fight began at five-star Hermitage Hotel in downtown Nashville where another source reported hearing “Sambora screaming obscentities at the top of his lungs” from their ninth-floor suite.

He also appeared drunk when he walked through the hotel at one point, the source said.

“I was wondering what the problem was,” the hotel guest said.

As Celebuzz first reported, Richards and Sambora vacationed over Spring Break together in Hawaii, along with Ava.
