Spotted Nicole Kidman and Keith Urban at Matsuri in the Maritime Hotel on Monday night, both demurely and casually dressed, and choosing to dine at a small quiet corner booth in the back near my table. Both intently conversing over sushi and bottled water with not a drop of alcohol in sight, and both seemingly very much in an amorous state...

Saw Quentin Tarantino at Bungalow 8 on the morning of Jan.5. No sight of Uma, but thankfully no sight of Shar Jackson either. To his credit, he actually seemed pretty normal, interacted with the plebeians and not as cracked-out as his embarrassing talk-show appearances would lead one to believe. He was with a non-famous but cute African-American lady who looked to be barely in her twenties.

Thursday, Dec 29, I was dragged to the women's denim sale on the 8th floor of Barneys by my gay friend. While he hounded for his size, Scarlett Johansson appeared with an ugly man. She was short, very small, and perhaps even pretty if she didn't have her nasal septum pierced. She looked like the bull in Madonna's Take a Bow. She didn't like that I was looking at her ring and scowled at me. Too bad for her, I'm really good at dirty looks.

In Peas and Pickles New Year's Eve night to get beer Juliette Lewis and boyfriend were introducing themselves to Mos Def (Real name Dante) Juliette: "So, do you go by Mos?" Dante "Yes of course I do, Honky Bitch." I added that last part.

A solo Keanu Reeves at the NYE afterparty at Joe s Pub with John Cameron Mitchell and Murray Hill. He came in to check out Michael Cerveris and some other Sweeny Toddies do a few songs. Sharp features, beady eyes, bearded, lean and embarrassingly enough, hot.

My friend saw Elijah Wood at 7B on New Year s day evening, playing BuckShot and trying to ignore all the girls who were milling around him. He is apparently really fragile looking. My friend yelled Froooooodooooo! at him, and he didn t even blink.

I spotted Kim Cattrall having brunch/lunch at Brasserie 360 (Third Avenue and 60th Street) around 12:15 p.m. on Jan. 1. She was seated on the second floor of the eatery with her (much younger) boyfriend and four or five other people. Perhaps because she was looking very un-Sex and the City in jeans and a simple beige shirt, no one was bothering her. She was, however, looking gorgeous and not very hungover shocking, considering it was the morning after New Year's Eve, and everyone else in the restaurant looked like they needed some serious Alka Seltzer and aspirin.

Spotted a bearded Jared Leto working out at Crunch gym on Lafeyette last night (1/3). Looked slightly bulkier, was wearing gray long pants and gray long-sleeve thermal type shirt, and held onto his jacket and fuzzy headwear throughout his workout. Very hot in person and amazing eyes. He kept talking on his blackberry in-between sets. Nobody paid him much mind, we were all just wondering why he didn t leave his 'berry in the locker like the rest of us.

Was walking past Tartine on West 11th Street on Saturday and spotted a blonde Topher Grace having lunch. When he doesn't have That 70's Hair, he's actually pretty cute. Didn't get a look at who he was with.

While waiting at the bus stop on Broadway and 60th, saw Kurt Russell and Goldie Hawn casually walking together towards Columbus Circle. Goldie (dressed in a white fur belted coat and Chanel sunglasses) was makeup-less and looked normal but totally itty-bitty. They stopped a few feet away from me I almost thought they were going to wait for a bus! but all was right with the world as they were just pausing to admire the new mulit-million dollar condos coming up along the park. Goldie remarked on how $4 million sounded reasonable for a two-bedroom place, and Kurt said he would call somebody tomorrow to check out the floor plans. After a few more minutes of rich-people chatter, they left and went into the Mandarin Oriental ... while I, on the other hand, boarded my bus and silently celebrated $1 holiday fare day.

I'm a little late on this one, but it's still noteworthy. Had some celebrity sightings courtesy of JetBlue while flying from JFK to Syracuse on December 22nd. Saw Tate Donovan with his new wife running towards their gate en-route to Aguadilla. At one point she mumbled something to him and he responded with an urgent motivational phrase that made her quicken her pace- I'm pretty sure they made their flight. As we began lining up to board I noticed Alec Baldwin standing guard in front of the flight desk, he was definitely hoping to be noticed. He had his young daughter with him, which I believe is the one he is battling Kim Basinger for. He was sharing his ipod headphones with a woman (I couldn t figure out if it was his assistant or his girlfriend) and was seat-dancing around like an idiot to the music when I walked by him en route to the bathroom. The daughter was really cute, looks just like her mom, but he seemed to be ignoring her for the assistant slash girlfriend slash ipod.

I'm typing this one a bit late, but I had almost forgotten about it. Saw Chevy Chase at LGA on Dec. 29th he was checking in at the NWA first class counter and wearing a huge parka. He was whisked through security in front of what must have been a thousand others waiting, but he's Chevy, dude. Then I get on my plane to Minneapolis, and there he is again in the first class cabin trying very hard not to make eye contact with anyone. Was he going to Minneapolis, or just connecting through there? Likely the latter. Oh then I saw Wanda Sykes shopping at Bloomingdale's the other day she looked very fit.

Jena Malone (Donnie Darko, etc), Nick Zinner and some unmemorable hippies from Maroon 5 all hanging out with each other at Mama s bar last Thursday. Yeah, makes no sense to me, either.

On Saturday 12/31 saw Alan Rickman (Professor Snape from Harry Potter movies) at the Sweeney Todd matinee. He's actually gorgeous in person with white hair, but it took everything in me to not run up to him and say, "You're going to kill Dumbledore." The night before I sat four rows in front of Molly Shannon at Sweet Charity. She's tiny and adorable. Shocking. Then I walked around the corner and wasn't paying attention so I literally almost took out David Hyde Pierce who wasn't completely as tiny as I expected.

Apparently the elevators at 1271 (Time Inc.) are working this morning just saw Rev. Jesse Jackson lumbering through a security checkpoint to catch a ride upstairs. Burberry scarf, wrinkled trenchcoat, very slow, sort of crippled-seeming gait. Was pressing the flesh of several (African-American) security guards, who were beaming in his presence. Boy, he looked old.

Sitting at Corner Bistro, Tuesday night Jan 3, saw Ozzy spawn Jack Osborne with big group chowing down on some burgers no big deal, looked like rest of crowd, and very young but then again, I guess he is

Nathan Lane eating alone at Bubby s in Tribeca at the corner table, 1/2/06 around 3pm.

Yesterday (1/2) at Duane Reade on Broadway between 8th and 9th Streets, saw Ian Somerhalder (killed off last season on "Lost" and now in "Dog Sees God" Off Broadway) in Duane Reade around 6:40pm. It was raining outside and he was looking to buy an umbrella. The clerk had apparently misdirected him and he was very polite saying he was unable to locate the umbrellas. He looked very young in person and had piercing blue eyes and naturally rosy cheeks.

Last night (1/02), while at Buster's Garage in Tribeca, my friends and I spotted Chris Carmack, better known as Luke for the OC. He seemed to be there to watch the Notre Dame game, but stayed through the Georgia game to hit on a trashy looking blonde girl in camouflage pants. When we left around 1am, he was one of the last 10-15 people there with camo girl.

In my office building on E. 42nd Street this morning (01/04) I was temporarily blinded by spangles and shiny skin. It was none other than Richard Simmons, dressed in an unseasonal blue and white sparkly tank top and bright blue short shorts. He was strutting his stuff and just loving himself, and stepped into the brisk morning air like he was stepping into his Sweating to the Oldies workout video. I was going to shout, "Hey it's Richard Simmons!" but I didn't feel like getting knocked out. I have no idea why he was here, except for the fact that I work in the same building as WB-11.
