Kelsey Grammer doesn't like to relive the pain of his failed 13-year marriage to Camille Grammer by watching The Real Housewives of Beverly Hills each Thursday night.

When Page Six caught up with the 55-year-old actor at the Blue Valentine afterparty at Top of the Standard in NYC Thursday, Kelsey got sheepish when asked if he tuned into the Bravo reality show.

"She can say it," he replied, deferring to his British fiancee Kayte Walsh, 29.

"We don't watch it," she answered curtly, just before the couple packed on the PDA in front of guests including Michelle Williams and Ryan Gosling.

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.)

Added Vanderpump: "Just take one step at a a game of chess, that way fewer mistakes and no regrets."
