Kelsey Grammer's ex wife Camille enjoyed a night out on the town with her former Real Housewives of Beverly Hills co-stars at Villa Blanca Restaurant in Beverly Hills, but she kept her mouth shut about today's wedding between Mr. Grammer, 55, and his 29-year-old fiancee Kayte Walsh.

When asked about whether she'll be attending Kelsey's New York wedding, the reality star just kept on smiling ... but didn't have an answer. We'll take that as a no.

Camille and Kelsey split after 14 years of marriage. For her bridal gown, Kayte will wear a custom Peter Langner for Mark Ingram gown, according to Access Hollywood.

As for the soon-to-be groom, he has arrived at the Plaza Hotel in NYC where preparations are well underway for his wedding tonight. The ceremony will take place at the Longacre Theater on Broadway.
