Not that the Frasier alum would like what he sees should he happen to watch an episode: Camille's Real Housewives costar Lisa Vanderpump recently slammed the actor's engagement on Twitter.
"Kelsey Grammer engaged? Did I miss something? Don't you think you should get divorced first?" Vanderpump tweeted in her costar's defense. (The couple's divorce has not been finalized, though his rep confirmed his engagement to Walsh on Monday.)
