· Saw Vince Vaughn at last night's (5/6) 10:45pm showing of Spidey 3 at the Arclight, rocking jeans and a black t-shirt. Dude is tall as hell and sporting a truly prodigal beer gut, pretty much looking exactly like he did in Wedding Crashers. He was with two buddies of his who I didn't recognize. Vince and buddies laughed heartily at the scene where Kirsten Dunst sings in a jazz club, being that she sounds like a gremlin. Only slightly better than my only other celebrity sighting, which was Weird Al Yankovic walking out of a Borat screening.

· I was walking to the Music Center tonight (Monday) to see Joan Didion speak and I accidentally walked right into a movie shoot in front of Disney Hall. Looked to my left and there was Steve Carell in a tux with a pretty lady at his side [ed. note: Anne Hathaway?] (and everyone in the scene was wearing tuxes). Turning to trusty IMDB... it was probably "Get Smart." So I totally ruined a take on the remake of Get Smart (especially since I was talking on my cell phone pretty loudly and got shushed as I walked by the crew). Awesome.

· Saturday, May 5, 2 p.m. or so... at the Downtown YMCA, a fit, trim and blonde-bearded Ryan Gosling working his abs. Lots of crunches before he moved on to pull-ups and a rather short bicep workout. I had heard through the grapevine that he lives downtown, but this is my first sighting of him at the Y. I'm sure his presence will increase female membership.......

· I saw Joaquin Phoenix at Skybar a little while ago (May 1) with 2 male friends of his. I saw some very average looking blonde girl walk up to him and talk to him as he was leaving for a cigarette break. Even though she was not cute he seemed to be flirting with her back and fourth and she walked outside with him. Twenty minutes go by and I am leaving the bar I see them talking and giggling to each other outside smoking. I thought he could do better than that chick because she wasn't exacrly the hottest cup of coffee in the cafe so to speak. They left in the same suv together but I think he may have been giving her a ride home. Just doing what any single man would I guess.

· 4/4: Mozza. Sumner Redstone, dining with another rich old man/used-to-be-attractive-trophy-wife couple. This is only worthy of privacy watch due to the 5-inch band-aid covering half of Sumner's face. Did he come to LA for plastic surgery or slip in the tub? We report, you decide.

· From Freaks and Geeks and the upcoming Knocked up, SETH ROGEN was having lunch with three friends at Taste of India in—heavens—Woodland Hills, last Tuesday, May 1st. He looked as pudgy and adorable as ever, with his chunky glasses and full & manly beard. Those Canadians do it for me.

Some weeks back: I caught ROBIN TUNNEY, late of Prison Break, coming out the Starbucks ladies' room at Vermont and Prospect. Short, and very pale she was.

· Sunday May 6, at the Real Food Daily in West Hollywood, Jason Schwartzman having brunch with a girl I didn't recognize, but who looked like a Breakfast Club-era Molly Ringwald—young, cute, red haired with a quirky style. They shared their meals (pancakes and a tofu scramble, I think) and talked quietly. Jason answered his cell phone, which I believe violates the restaurant's no cell phone policy, but since we were seated outside on the sidewalk patio, I suppose that rule is relaxed.

· Spotted Jason Schwartzman at Pinkberry on Melrose. He's utterly adorkable and I tried to check him out without seeming too obvious. Good thing I was wearing my obnoxiously huge sunglasses. Maybe that's why they are so popular in LA.

· Thursday 5/3 Waited enlessly for a chicken sandwhich next to Seann William Scott at the weho koo koo roo. Thrilling right? He was casually dressed, and surprisingly taller than expected, he's 5'11" according to celebheights.com, who knew? sidebar: what is up with them constantly redecorating that place and the win-a-shitty-dvd carnival game in the corner? Then later that night I was on the balcony and in the elevator next to Lindsay Lohan for the Britney Spears show. Lindsay looked great, didn't drink and was also texting a lot. All eyes were on her until Brit hit the stage. That show was a hot mess!

· Sunday afternoon (5/6) I drove past Adrian Grenier as he walked down Sunset Blvd in Silverlake. He had on a black t-shirt, jeans and massive nothing-to-see-here-folks-I'm-just-a-normal-citizen-like-you sunglasses. Very skinny arms. He must have an awesome stylist on Entourage, because he had some serious frizzy bedhead 'fro going on. He was carrying a small package under his arm and walked with a male friend. Resisted urge to scream "Aquaman rules, I love you, Vince!" out the window. In LA art imitates life imitates art, I guess.

· saw David Boreanaz and Dylan Walsh at my gym (Equinox on Sunset Plaza) last week...

· Was slumming it on Third Street with an out-of-town friend. When we got up from our wine-heavy lunch, I saw that I'd been blabbing on about my ex-boyfriends about 6 inches from Rosanna Arquette's ears. Guess I ruined all my ex-dudes' chances with her...or maybe she's the one that could make them change. Either way: yawn.

· today (5-7) lunch time saw Matthew Modine at Staples in Hollywood. He is very bottle blonde (to blonde for his age) and when i smiled at him he didn't smile back.....maybe he was sad to be alone at staples in the middle of the day.........

· Friday 5:40pm Sunset and El Centro

Walking East on Sunset: Chris Robinson of the Black Crowes (without Kate Hudson I don't even know if he will make this)

In any case he was walking down Sunset sandwiched between two men. Kind of a sleazy area of sunst. My guess is he was at a nearby recording studio. I wanted to yell "hey Chris Rock, how does it feel to have Owen Wilson banging your wife" but I wasn't sure how he would take that.

Special De La Hoya-Mayweather Edition:



· 5/5/07: Sure, celebrities at the De La Hoya-Mayweather fight were like Lana Clarkson's teeth fragments in the foyer in Alhambra, but here are strictly the people I could see from my seat: Jack Nicholson, Sen. John McCain, Tobey Maguire (trying to pretend he didn't notice they spelled his name "Toby McGuire" when they showed him on the overhead video screen _ and on the weekend of his greatest cinematic triumph), Jennifer Lopez, Jay-Z, Leonardo DiCaprio (wearing a White Sox cap), John Cusack (also wearing a White Sox cap), Eddie Murphy, Michael Jordan, Magic Johnson, Denzel Washington, Matthew McConaughey, Will Ferrell (he's at that Bill Murray point in his fame now where he doesn't even do anything funny, and people still laugh hysterically), Jim Carrey (hair 15 years younger than his face) and Jenny McCarthy, Sacha Baron Cohen, Russell Crowe, Chris Tucker, Eva Longoria and Mario Lopez (hahahaha), Helen Mirren (sooo fuckable in white) and Taylor Hackford, John Madden, Luke Perry, Wyclef Jean, Kevin Dillon, Kevin Connolly (hey, he's short!), Dominic West (The Wire, so cool), Brian Grazer (I think/hope), Bob Saget, Ron Howard, Mary J. Blige, Michael J. Fox, Tom Jones, Charles Barkley, George Lopez, Charlie Sheen and the best of all, Tommy Lasorda laying off the lesbian porn for a few hours.
