Kelsey Grammer has accidently revealed he was seeing another woman before he officially divorced his ex- wife, Real Housewives of Beverley Hills star Camille Donatacci Grammer.

On Late Night with Jimmy Kimmel, Grammer, 56, discussed how he met his current British wife Kate Walsh, 30, in Dec. 2009. He said that he was on a flight to London when he met Walsh, who was a flight attendant. The two hit it off and, according to Grammer, met for coffee and a “magical night” in London.

“It was very romantic, she was working on the plane,” Grammer told Kimmel in an interview.

“We went out for coffee several days later and had this magical night in the snow in London around Christmas time. It was two years ago.”

What Grammer seemingly didn’t remember before speaking was the fact that he was still married to Camille, 43. According to The Daily Mail, Camille alleged Kelsey did not tell her he wanted a divorce until June 2010 via text message. She claims the message read: “I don't want to be married anymore.”

Camille still maintains the surname Grammer.

Grammer and Camille were spotted together, during the time he said he met Walsh, at the premiere of Camille’s reality show and again at the 2010 Tony Awards.

The Emmy Award winning “Frasier” actor has had a sordid love life. After divorcing his first wife, he married stripper Leigh-Anne Csuhany. Csuhany and Grammer divorced after just one year of marriage and allegations of abuse by Grammer against Csuhany. He then married Camille, a former Playboy model. The two have taken cheap shots at one another in the media including Grammer telling Piers Morgan he got Camille the job on Real Housewives as a "parting gift," according to People magazine, and Camille criticizing the size of Grammer’s manhood to TMZ.

“The Real Housewives of Beverly Hills” star told The New York Post, “I wish Kelsey and Kayte the best . . . This is a bittersweet day for me. This was painful and I'm still healing, but I am ready to move on with my life.”

Grammer and Walsh married only 15 days after his divorce was finalized Feb. 25, 2011. The couple lives in New York. Grammer has two children with Camille Grammer and one child with his first wife, Doreen Alderman. He also had a daughter with a former girlfriend in 1992.
