I know you were worried she'd leave, but it looks as though Katie Holmes might be staying here in New York for good. And she's keeping Tom with her.

Their simmering rivalry was thought resolved. But with their new, respective designer ads unveiled on the same day, Katie Holmes and Victoria Beckham appear to have retrenched in a battle for This Year's Look.

New Year, new jobs: Tom Cruise has assigned Katie Holmes reproductive duties, Alec Baldwin's famous voice finally got him his dream job and Lauryn Hill is testing new mounts.

Was it a violin string snapping? The long, low moan of a siren? What was it—what sound, what feeling—that told us that Katie Holmes was leaving New York?

Katie Holmes is infusing many, many dollars into the New York economy. We're sure of that. But just how much, exactly? Is she saving New York? If the low current estimates are right, no.

Kristin Davis, whose Wicked Models escort agency counted former governor Eliot Spitzer as a client, thinks Britney Spears could earn $1,000 an hour in the world's oldest profession.

Tom Cruise bought a special car to ward off anti-Scientology protesters and other agents of Xenu; Britney Spears can ward off the blues with the sari from her new boyfriend.

All those paparazzi pics of Tom Cruise leaving his East 13th Street apartment building with Katie Holmes? He's just visiting, apparently. According to British tabloids, Cruise "now lives in a separate location" from Katie Holmes and their daughter Suri, and the family travels by "bomb-proof car," due to death threats by groups opposed to Scientology. Just in case that sounds like a perfectly sensible reaction on Cruise's part, you may want to keep in mind that it's also rumored he spent $8 million to construct an "underground bunker" on his property in Colorado.

• Assuming you have access to a very good house cleaning service, the Kardashian residence in LA is now on the market for $3.395 mil. [TMZ]

It wouldn't be Christmas Eve without fighting: Alec Baldwin supposedly slammed Tina Fey's body; Paris Hilton's uncle got attacked and robbed in his home and Nicole Kidman was haunted by Katie Holmes.

Lauren Conrad leaving Butter with Holly Montag ... Leona Lewis filming her new music video in Brooklyn ... Katie Holmes and Suri shopping at J.

Everyone is speculating wildly: The Post asks if Tom Cruise gave his wives cold sores; Hollywood reporters accuse their boss of naughty flights and Madonna thinks a new baby can maybe fix everything.
