Kelsey Grammer Claims He 'Didn't Have Sex for a Decade' While Married to Camille Grammer (WATCH VIDEO)

"The Real Housewives of Beverly Hills" might not be airing, but Camille Grammer's life is still filled with drama.

Her ex-husband, Kelsey Grammer, 57, who she's been split from for more than two years, took a dig at his 44-year-old former wife, during his Sept. 10 appearance on Conan O'Brien's show.

While Kelsey was clearing up rumors about his extramarital affair with his current wife, 29-year-old Katye Walsh, he insisted they didn't consummate their love for several months after meeting.

"Well we kissed that night...we didn't do anything much more than kiss for several months," Kelsey told the "Late Night" show host. "I just wanted to clear that up... she was worth the wait."

O'Brien interjected by saying, "I would think that would be difficult."

Kelsey took a jab at his ex and sarcastically replied, "Well, for a guy that hadn't had sex for a decade it wasn't that hard!"

The "Frasier" star has gotten divorced three times, but did not sign a prenuptial agreement with Camille, who he was married to for 13 years. Camille could receive $30 million in the settlement, according to the Daily Mail.

Kelsey has been working the talk show circuit promoting the return of his Starz series, "Boss" and, while he has stopped referring to Camille by name, he continues to gripe.

Last month, sat with his British flight attendant bride and newborn baby Faith, told Oprah Winfrey that he thought he owed Camille "fame" and got her a spot on "The Real Housewives of Beverly Hills."

"Because she'd given up so much to endure this life with me," Kelsey said sarcastically, according to the Daily Mail.

Camille, however, told HLN's Joy Behar that if her reality show fame was a gift then, "thank you, Kelsey, for the gift of humiliation for the first season."

The former Playboy model, who has since moved on to bankruptcy lawyer Dimitri Charalambopoulos, said the first season was horrible because Grammer left her for Walsh while she was filming.

In the past, Camille made public allegations that her former husband was a cross-dresser and that they "just didn't mesh sexually."
