Actor Kelsey Grammer refuses to utter his ex-wife Camille's name after enduring a bitter and public divorce and custody battle in 2010.
The former Frasier star recently invited TV mogul Oprah Winfrey into his Los Angeles home for a sit-down interview with his new wife, Kayte Walsh, but when quizzed about his failed third marriage to Camille Grammer, the actor insisted on simply referring to her as "that person".
In a short video clip of the candid chat, which will air on Oprah's Next Chapter on Sunday (26Aug12), Grammer admits he "lacked the courage" to tell Camille their 13-year union was over, but accepts that she played a big part in helping him achieve such a high level of fame taking care of their two children while he focused on work.
He says, "I did believe that I owed something to that person, that I owed fame."
Picking up on the odd tone as he discusses his ex, Winfrey asks, "You won't say her name?" to which he replies, "No."
With a hint of sarcasm, he then explains, "(I owe her fame) because she had given up so much to just endure this horrible life she had with me."
During the interview, Grammer and Walsh, wed in 2011, also introduce Winfrey to their baby daughter Faith, who was born last month (Jul12).
The actor also shares two children with Camille, while he has another two adult kids from previous relationships.
