Kelsey Grammer and his wife of 13 years, Camille Donatacci Grammer, announced last week that they are splitting up, and now everyone wants to know the real reason why. "Camille and I shared many wonderful things throughout our years together," the actor said on his website. "There were just a few things that we couldn't work out." So, what couldn't they work out and, come to think of it, why did she file for divorce? Sources tell me it's all about reality ... TV, as in Camille's desire to snare some fame of her own on the upcoming 'Real Housewives of Beverly Hills.' I'm hearing that Kelsey wanted nothing to do with it. More on the Grammers, plus an exclusive first look at a different type of housewife (the ravishing Vanessa Williams on 'Desperate Housewives'), after the jump!
