This edition of Hollywood PrivacyWatch brings a very special Stallion sighting, an especially social Office star, a veritable galaxy of airport celebrity and other high-wattage fruits of your spying labors. Remember, each and every PrivacyWatch relies on your restless, roving eyes, so keep those tips coming with either "Sightings" or "PrivacyWatch" in the subject line. We appreciate all of your surveillance and couldn't contemplate leaving any of it behind. Among those observed in this installment: Owen Wilson, John Krasinski, Amy Adams, Ryan Phillippe, Neil Patrick Harris, Jared Leto, John Legend, Jonah Hill, Martin Landau, Chloe Sevigny, William Fichtner, Ron Livingston, Mekhi Phifer and more.SATURDAY, SEPT. 20 Went to see The Women (the play, not the movie) in a theater near downtown, when I saw MARTIN LANDAU (looking dapper for 77) talking with JACK STEHLIN from Weeds. I was going to list some Martin Landau credits but imdb has 155 of them and I didn't know what to pick. Loved him in Ed Wood, though. THURSDAY, SEPT. 25 Sept. 25 [At the] Aloud event at the LA Central Library, I spotted ERIC IDLE and a companion enjoying the battling accents of ARIANNA HUFFINGTON and BERNARD HENRI-LEVY. Looked like ALAIN GIRAUD may have been there as well, but I can't be sure. Idle and the Giraud lookalike repaired to Cafe Pinot for a post-talk meal, I expect to be joined by BHL and AH, since they were chatting on stage after the event. FRIDAY, SEPT. 26 It was a transatlantic Dundler-Mifflin meetup on Friday (9/26) at the Magic Castle as JOHN KRASINSKI was hanging with STEPHEN MERCHANT (from The Office UK and Extras). The former looked way hotter and less goofy in person and the latter is a good seven feet tall and was chatting up AIMEE MANN. I was dancing up a storm during the MSTRKRFT show at the Henry Fonda Theater when a guy walks right up and blocks my view. He turns around to face me and starts to mess around with his phone. I’m just about to call him out for being in my ‘personal space bubble’ (the dance floor was pretty empty by that time) when I realize that it’s JARED LETO! He looked a little rough: hair slicked back into a pony tail, scruffy facial hair, black army boots and red flannel shirt tight around his waste. '90s style flashback. I felt kind of sorry for him; Jared seemed a kind of bummed about not getting any celeb-like attention. SATURDAY, SEPT. 27 A day earlier on Sept. 27, we saw RON LIVINGSTON and MEKHI PHIFER at the Shane Mosley-Ricardo Mayorga fight in Carson. They weren't together, dammit; Ron had his usual stubble and a third-row seat, while Mekhi was up on the concourse chatting with former fringe NBA player CHRIS MILLS before the main event. SUNDAY, SEPT. 28 After watching my best friend perform an acoustic set at Level 5, someone commented "Hey, there's Jim from The Office." Sure enough, I turn around and there's JOHN KRASINSKI chatting it up with a very cute redhead and an equally cute blonde. OWEN WILSON at The Other Room during the Abbot Kinney Festival. Fairly inconspicuous. He sat and texted the whole time, probably an hour two. I never saw him look up once. My trashed friend asked him what was going on with all the texting. Owen didn't understand the question. I think he left before the guy was killed outside. I saw that happen, pretty messed up. Saw JONAH HILL at the Abbot Kinney Festival on Sunday the 28th. He was in the line for Sausage Masters but didn't seem to purchase anything. He must be on a diet as he's looking a little more svelte than usual. He was very sweet... Saw BRENDAN SEXTON III at Sabor y Cultura cafe in Hollywood today. It was kind of dorky/endearing, there was a group of middle-aged gamers there and he went right over and was totally into it. He was with a tiny blond who was then forced to observe the gaming as well. I don't think anyone else knew who he was, I was just really into Welcome to the Dollhouse back in the day... It feels like cheating to submit sightings from the A terminal at the Burbank airport, since celebs and plebes alike have to walk down that same narrow hall to exit the sad old barn, but what the hell. On Sunday night around 9 p.m., the following people walked by separately in a 4-minute span, presumably all coming off the late JetBlue flight from JFK: WILLIAM FICHTNER of Prison Break, wearing athletic-type clothes and walking so fast his hairline receded; NEIL PATRICK HARRIS, looking awesome in a black T-shirt and gaily chatting with some dude; CHLOE SEVIGNY, mousy-haired and depressingly dressed like a normal person; and finally AMY ADAMS, toting her own overstuffed Louis Vuitton bag and staring grimly ahead while marching with an entourage of at least two other chicks. No smile, no eye contact, still smoking hot. Just got off AA115 from LHR to JFK. JOHN LEGEND was traveling in first class. A wee bit shorter then I anticipated. Saw everyone’s favorite ex-lazy postman WAYNE KNIGHT at the Vendome Liquors in Toluca Lake on Sunday evening. Would have liked to say hi, but he was busy getting advice on red wine from one of the employees. Oh well. MONDAY, SEPT. 29 RYAN PHILLIPPE with BFF and business partner BRECKIN MEYER at Nate 'n Al's in BH on Saturday morning.
