Popeater’s Rob Shulter has supposed insider knowledge of some trouble in Kelsey Grammer’s very new very quick marriage to 29 year-old British former flight attendant, Kayte Walsh. According to Shulter, the two are disagreeing about where to live, with Kayte hoping to stay in New York and Kelsey planning to move back to Los Angeles to work on a project and be closer to his kids. (Probably in that order.) Kayte is likely to suck it up and do whatever her new sugar daddy wants, but it’s an indicator that their marriage is already showing cracks after a whole two weeks.

Kelsey Grammer and his fourth wife, Kayte Walsh, have only been married a couple of weeks and already the new Mrs. Grammer is starting to understand that being married to Kelsey isn’t as easy as you might think. Sources close to the pair tell me they’ve already stumbled upon their first rift — and it involves about 2,800 miles and an ex-wife.

“Kelsey wants to move back to LA to be near his daughters and start working on a new TV project with Starz,” an insider tells me. “But Kayte would rather stay in New York where she has close friends and is far, far away from [his ex-wife] Camille.”

The ‘Frazier’ star will win in the end, friends say, but the disagreement so early on “should be a warning of what is to come.”

The May-December couple (he’s 55, she’s 29) have been laying pretty low since their Feb. 25 wedding, which came just two weeks after he finalized his divorce from his wife of 13 years, Camille, 42. But on Friday, the pair emerged looking happy as can be as they rambled around midtown New York and Central Park. In many of the pics, Kelsey obliged snappers by laying a few kisses on his bride.

Maybe Kelsey will look at these photos of a beautiful day in NYC and change his mind about heading back to Los Angeles and the realities of living near an ex-wife? Not likely.

“Kelsey has an enormous ego and definitely likes being the boss,” my source tells me. “Everything goes great when your answers is ‘yes’ to him.” And right now, he’s saying “yes” to being near his young kids with Camille, 9-year-old Mason and 6-year-old Jude.

It’s been a drama-filled first chapter in the story of Kelsey and Kayte, who became pregnant but lost the baby while the actor was still very married to Camille, now a star of ‘The Real Housewives of Beverly Hills.’ Kelsey announced he was engaged to Kayte and said, “We are in love and see no reason to postpone our happiness any longer.”

You know that Camille is Shuter’s source and she’s repeating some gossip she overheard from the nanny. Camille has been interviewed by Shuter a few weeks ago and she probably has him on speed dial.

I disagree with the claim that these two have been keeping a low profile since their wedding. Those kissing photos are just as staged as their vacation photos. I also doubt that Kayte and Kelsey will be breaking up anytime soon. Kayte has her career path mapped out for her, and it involves about ten years by Kelsey’s side, followed by a divorce when Kelsey inevitably stops idealizing her and replaces her with a younger model. By that point she’ll be a very wealthy, spoiled, botoxed, up-her-ass woman. It remains to be seen whether she’ll be a NY or an LA wife and it matters little.
