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."
