Kelsey Grammer's estranged wife Camille realised the former Frasier star had taken a new lover last summer (10) when a doorman denied her entry into the actor's New York apartment building, telling her she was "not Mrs. Grammer".
The reality TV star had no idea her marriage was in trouble when Grammer jetted off to the Big Apple to embark on a theatre career on Broadway.
But, following concerning calls from mutual friends, she challenged the actor about the state of their marriage and he told her their 13-year romance was over by phone.
It later emerged he had found love with Kayte Walsh, and the couple is now engaged to wed.
Camille's heartbreaking phone call was captured on camera for her show The Real Housewives of Beverly Hills and, in an episode which aired in the U.S. on Thursday night (20Jan11), she explains how she discovered there was already another woman in Grammer's life after attending the Tony Awards as his date.
She recalls how she was stopped by a doorman as she entered Grammer's apartment building, who insisted, "You're not Mrs. Grammer."
She protested and was forced to prove her claim by producing her identity card, which eventually gained her entry.
She says, "It was so humiliating."
