Sat adjacent to Cameron Diaz sans Timberlake dining at the Four Seasons at 10pm. She was with two gentlemen that looked like lawyers or family. Her hair was dyed dark.
Just saw Jessica Simpson at my Hotel 50 Central Park South, she was covered in security but heard her say something about going to a photoshoot in Brooklyn!

Saw Alec Baldwin at The Who concert last night wearing retro glasses and rockin out with his gorgeous girlfriend, long hair, incredible body...really into the music and each other, never sat down, danced and sang through the whole thing, held hands. Nice!

I saw scruffy-looking nerf-herder Harrison Ford at City Bakery at 5pm yesterday. He looked so buff and hunky for a man over 60. (Training for Indiana Jones 4 perhaps?) Then not 10 minutes later, Jimmy Fallon walked in with a male friend in tow. Jimmy seemed oblivious, but the friend was your typical smug too-cool-for-school starfucker type.

Milla Jovovich was there, as well; looking gawky and well-past her prime. I bribed the server and was informed it was a get-together for "Vogue" magazine.

Saw Jessica Biel yesterday (9/18) walking west on 59th St., between 8th and 9th ave. Dressed way down in a baseball cap.

Marc Jacobs at David Barton Gym. MJ looks VERY cute-hot/ nerdy and vulnerable and sexy, which is a lot like his clothes I guess. I'd hit it. Ethan Hawke at same gym. Less pasty, healthier, than he appears in photos. Handsome and kinda-focused, kinda-not on his workout. But unlike many of the bitter queens at DBG, he's a polite gym goer. He racks his weights, thank you very much.
September 18th, Monday night, 9:30: I spotted big-cheese Harvey Weinstein, looking big and cheesy, at a party with 30 people at Japonais on 18th and S. Park; he was flirtatious with a tall, beautiful black model, who obviously wasn't there for the food.

I just saw Senator Chuck Schumer at the Carnegie Deli. He was soo nice and took literally 15 pictures with the waitstaff. I had no clue who he was until I asked his bodyguard...then I got my pic too! He's very tall and good looking for an older politician. Is there an election coming up or something, or is he just really that nice?

Dick Gephardt on the uptown 6 train at 6:45 wearing blue blazer and a red tie and chatting with female companion. They got off at 51st street and seemed to be in a hurry.

Anne Hathaway 9:30 AM today - 53rd St. between 6th & 7th, in a black skirt suit and some major heels - talking on her cell phone; paler and taller than I expected

9/21, 6ish, Ted Turner walking towards his new bison-burger enterprise on 51st. Taller and more gaunt than I would've thought. Tried to catch his eye but he had this faraway, sort of stoned look. All around freaky, but I would still like him to impregnate me so I could live off the child support.

I saw Jennifer Love Hewitt eating sushi at Ruby Foo's in midtown last night at 10pm. She was with a group of 8 friends and one of them seemed like her boyfriend. Her hair was immaculate as was her incredibly skinny body.

Saw Martha Stewart walk into Cafe Gray at the Time Warner Center around 7 pm Thursday night, with half a dozen fawning hostesses trailing after her. One of the few celebrities who looks taller than you'd expect.

This morning, on the way to work, I saw Ivanka Trump. She was on 58th street, walking toward 5th Ave (and Trump Towers). She was listening to her Ipod, looking incredibly chic, and endearingly normal.

I saw Mary Kate Olsen with entourage at the Rose Bar at the Gramercy Park Hotel last night. She was very skinny, wearing shorts with pantyhose (weird), and looking twelve. She seemed very normal and her friends were nice.

Caught a glimpse of Julianne Moore last evening at about 7:30 pm, whilst she was dining outdoors at Bar Pitti with a male friend.

Matt Dillon at my Starbucks on 82nd and Columbus. Dirty hat, ripped jeans, on phone trying to do the incognito thing. Oh dear god, I think he's reading the New York Post! Gasp!

I just saw Danny Glover walking down 5th aver at about 21st street on my way into work at 9am this morning. Was taller and older than I expected.

11th & university, 6 pm—spotted Keri Russell with an unidentified male friend looking particularly nondescript, pink tank with her hair in a messy bun. Boring.

Ok... I think I am Mary Stuart Masterson's only fan, so when I saw her last night on 30th and 7th, jumping out of a cab and running directly into the subway, I got very excited!

Fresh from her appearance on the CBS Morning Show, I saw Marg Helgenberger accompanied by a woman with long brown hair in the shoe department at Bergdorf Goodman. She looked great in a brown leather blazer and jeans cuffed at the knee.

Thursday, September 21, W. 18 & 10, Usher himself on the rink at The Roxy. Moved very well on wheels, and didn't have massive entourage.

Saw Harvey Fierstein last night at Martin Shorts show, Fame Becomes Me. The show was so-so until Edna (HF) was pulled on stage to be interviewed by Jiminy Glick. Hysterical. And charming as all get-up.

I saw Ryan Reynolds at Times Square. He is REALLY tall and he was walking down to the 40th street. He was looking really casual. Some guys spotted him as well - he didn't react to their shouts.
9/18, 8pm—saw Josh Hartnett walking down Thompson, wearing a green hat, gray t with the sleeves cut off, shorts, listening to an ipod. His face is so so, but he was seriously ripped. Maybe just coming back from the gym?

Last night at 8:00 I was slurping noodles at Sobaya on East 9th Street when Noel Gallagher of Oasis came in with a blonde woman. The restaurant collectively gasped. They said hello to another couple that were already eating and went to sit at the bar. Not five minutes later Jim Jarmusch walks in and joins the celebrity magnet couple, who were unfortunately unrecognizable to me and my dining companion.

Walked past Liza Minnelli last night around 8 pm on 80th and Lex. She was dressed down in sweats talking to some older dude. Has she ever had a different hair style? Ever?

Haley Joel Osment at 1am signing a girl out of his NYU dorm building. Short as ever, pretty girl though.

Koi Bryant Park hotel, 8pm: Jane Pauley, still really pretty. With two girlfriends. One looked like Caroline Kennedy, much prettier than pictures. They seemed to be having very good time. We like Meredith, but Jane, we miss you.
