After an acrimonious divorce battle, Kelsey Grammer has said that he no longer wishes to discuss his former marriage to ex-wife, Camille Grammer, who starred on two seasons of “The Real Housewives of Beverly Hills.” But on several recent talk show appearances, Grammer has continued to do precisely that.

Grammer, 57, allegedly walked off the set of “Piers Morgan Live” last week because Morgan showed him a picture of Camille. The host later tweeted, “So, Kelsey Grammer saw a photo of his ex-wife Camille in the open to our show and legged it. Extraordinary. Never had this happen before." But the actor was more candid during a recent taping of “Anderson Live,” revealing to the talk show host and news anchor that he regrets staying married to Camille for as long as he did.

He also claimed, during a recent interview on “Conan,” that he “hadn't had sex for a decade” during his marriage to Camille.

Kelsey and Camille Grammer were married for 13 years. Their split, or as Grammer alleges, a fictionalized version of it, was included on “The Real Housewives of Beverly Hills.”

When asked to respond to a Twitter question about whether the “Frasier” actor regretted anything in his life, Grammer responded “there’s several things I regret.” He named not spending more time with his daughter, and not telling his new wife, Kayte, that he loved her more.

Cooper then got more specific in a follow-up question, asking “I’d been a big ‘Real Housewives’ watcher – did you ever regret any of those scenes you were in? Because some of them were very awkward. Like when Camille went and visited you backstage, there was this really awkward scene and I felt for you in that scene.”

“I was trying to pretend things were normal, for the sake of somehow letting her have that moment,” said Grammer, of his decision to appear on the reality show. "It was just ill-advised. It was the wrong decision, and I should have come home from England when I first met Kayte and just said, 'Listen, I've met somebody and this hasn't been working for a long time.' I regret not doing that."

“I thought I could do something nice, some parting thing and so it was very painful and uncomfortable. It was uncomfortable for Kayte, it was uncomfortable for all of us,” he added.

Grammer also shared similar insights in August, when he appeared on “Oprah’s Next Chapter.” "I stayed [in the marriage] because I’m a stubborn cuss,” he told Oprah. “I was not in it, or happy in it for a long time. It was pretty much over as soon as it began."

According to a Radar Online report on Wednesday, Camille is disappointed with her ex-husband’s public remarks, and told the website, “"Kelsey and I shared a life together and have two beautiful children together, and I just wish he would stop the constant barrage of negativity towards me as it's bad for our children and our respective families.”

“I would hope that Kelsey would say something positive about our life together, so we can be amicable. I have absolutely no ill will towards Kelsey, I keep focused on what is ahead and I don't look back. I have happy memories about my time with Kelsey, yes, there were sad times, but I focus on the positive times for the sake of our children. I'm just not a negative person."
