· Last night I was glaring down some RNC delegates outside the Plaza when I noticed Mary-Kate Olsen walking down the street with a middle-aged guy. She was wearing a beige, boho top and pink 1970s divorcee-style sunglasses. The best part is that the guy she was with was saying, "It's Musharraf! You know who Musharraf is, don't you?" while she looked blankly ahead. She passed by and I was unable to establish whether or not MK follows Pakistani politics.

· just saw mk olsen walking alone on prince st., eating potato chips, looking skinny but not scary skinny.

· I just saw a surprisingly old, wrinkly and ragged looking Chris Kattan buying HIS OWN SNL GREATEST HITS DVD at the Megastore in Union Square just after midnight (to ensure he got a copy the second it came out)...Don't they send him a preview copy or something? Jeez...tough times I guess.

· we saw elvis costello @ the met on saturday afternoon with, probably, his wife diana krall (i've no idea who that is, but my fiance seemed to know). they were just exiting the medeival art hall. i was pretty excited, but some other guy already stopped him and was getting an autograph, elvis seemed pretty nice about it.

· Saturday afternoon at the Met (the museum, not the opera house), Elvis Costello, standing in a corner, across the hall from some bathrooms. Awaiting the emergence of the former Miss Krall, perhaps?

· Was sitting in the NY Times club suite box on weds at the US Open watching Federer play Baghdatis, when Matthew Perry walked right in front of us. He glanced at the court then was told by the security guard that he couldn't be there. Chandler scowled at him and didn't crack any jokes and walked out of the area with his blonde female friend.

· i think i saw karen o and spike jonze turning on to st. marks from avenue a just now (sunday, 2:30ish). at first i just noticed a black-haired ugly-hot hipster girl in what appeared to be a black-and-white shortie jumpsuit. as i was rolling my eyes at this gesture towards retard chic, i caught a glimpse of her rat-faced, ugly-hot companion. He was wearing a striped izod shirt and was about her height and had one of those anti-haircuts. Yes, definetely a hipster power couple, and truly equally matched in terms of ugly-hotness.

· 9/04/04: Beyonce and Jay Z dancing and singing standing on the couch @ Marquee Saturday night. They were dancing to Crazy in Love ...obviously the song they did together. They gathered quite the crowd so I was a little embarrased to watch it all go down, but it was amazing. Beyonce is very bootilicious.

· Saw Chloe Sevigny (without her umlaut) at the Siouxsie Sioux show last night at the BB King grill on 42nd street. She had some BIG ass 80's style prescription glasses on that was pushed through her greasy blonde hair in a "cousin it" style. skinny ass legs in her black dress and black jazz boots or somesuch. i couldn't decide if she was trying to be a geeky skank or a skanky geek. no word if she was blowing Budgie in the back after the show. Siouxsie would've torn her a new one i'm sure.

· so I'm standing outside the Black and White on East 10th street on Sunday afternoon waiting for a friend and I see Chloe Sevigny (sorry, I can't manage to produce and umlaut on my computer) approaching. I think to myself, "that's cool. there's Chloe Sevigny" and then she stops in front of me and makes a confused face. I'm like "Um, hi" and she says "it's closed", referring to the bar. I say "yup". she inquires at what time the bar opens and I say I haven't the slightest idea as I was supposed to meet someone there as well. She smiles, shrugs and walks off. A minute later, she returns and says she has called her friend who works there and it doesn't open until 6:30. (it was 5:30 at the time). She then starts shoving a small package under the metal gate of the bar. She was concerned that someone would see it. I assured her that the only person who saw her leave the package was me and I promised not to take it. She smiled and walked away. I then took the package and ran. no, just kidding, I didn't really take the package. I made that part up. She was delightful, even if she has had her mouth on Vinnie Gallo's penis.

· Just out to lunch, I spotted Chris Robinson of the Black Crows walking along Cooper Square by St. Marks with some non-descript dude. Robinson was talking really loud about something; he was wearing a baseball cap and aviators.

· I was on the lower level of the Union Square Virgin Megastore, in the soundtracks and country section, when I walked by Ric Ocasek (shaggy hair, black pin-striped jacket, total laid back rock 'n' roll). The best part was that as I rode the escalator up to the main level, I realized the DJ must have seen him as well...the Cars' "Tonight She Comes" was playing on the PA system. Too funny!

· Michael Phelps, the cocky olympic swimmer, was at suede tuesday night, i was washing my hands next to him, and the guy on the other side asked him how many girls he had "done" while in greece. He responded with a confident "7 man, and they were all hot." he looked nasty.

· Saw Eric Clapton with his young, beautiful wife and their 2 very young toddler children, yesterday (Thursday,) around 3:30 pm on 5th Ave and 59th Street. They were walking up to strangers asking for the nearest toy store. (It appeared they had tried for FAO Swartz, but it has been closed.)

· saw sam rockwell saturday night at don hill's..shorter than i expected and seemed friendly enough..seen him talking to some b-grade soprano on the street as well as i was still drinking later that evening..530 ish..saw him leave with a male friend ..him walking and friend with bike east on spring street.

· Katie Couric at J. Crew in Rockefeller Center. Wearing blonde highlights, orange-y T.V. make-up (or is that bad tan??), and stiletto black-and-white mules. Gabbing with strangers in the store and all around acting like the center of attention.

· Saw Al Franken on Saturday night (early) while I was eating outside at Niko's. In the W 70's. I didn't recognize him, but some other guy did and started yelling how Air America sucks. But then that he loved what Al was doing on MDA, and thanks for that. Al turned around after the "Air America sucks" -esque comment, but acknowledged the MDA one, said thanks. He looked like what he really meant was, "shut the f*ck up." I was happy that yet another celebrity, who literally walked right past me unnoticed, got pointed out by a stranger, but I also wanted to punch the man who hecked Al Franken, because he was loud and annoying the whole time. Kick-ass mezedes, though.

· On the downtown A last night (9/6) around 8pm, I had the bizarre pleasure of sitting next to Doogie [Neal Patrick Harris] (looking pretty old to be truthful, and gabbing pretty loudly) and what looked to be visiting parents/family (including a much cuter hipster looking younger dude) He glanced in my direction a few times, pimping for recognition (which I returned with a smirk- I was more a vinnie fan). True to NY weekend fashion, the L was not operating and we all ascended to the street- me to the awaiting M14- and his party to a cab down 14th.

· Early Saturday night at Nobu, we saw Andy Roddick with a huge group. He was sitting down but is clearly a very big boy. He was tossing his head back and cackling about something. Maybe he was amused by how freaking hot he is.

· This morning I saw James "The Ragin' Cajun" Carville jogging up Fifth Avenue, likely taking advantage of the newly Republican-free streets. He was sporting grotty black shorts, a red t-shirt and white gym socks pulled up to his knees. I didn't notice his sneakers, but you couldn't miss the X-TREME sunglasses he was wearing.

· Sunday afternoon at Our Name is Mudd on Greenwich Ave. I spotted Christian Finnegan and his very very thin girlfriend. At least I wasn't the only loser painting pottery on a holiday weekend.
