In a special edition of #stalker, Michael "Kramer" Richards was spotted this evening in the Union Square subway station. What he was doing there is a mystery, though:

Celebrities have descended on Central Park. In this weekend's #stalker sightings: Blythe Danner, Vince Vaughn, Amanda Peet. Elsewhere: Tinsley Mortimer, Owen Wilson, Mary-Louise Parker, Zach Braff, and Matthew Broderick.

Every day, celebrities are sweating on the treadmill in your gyms, hogging tables in your restaurants, and shopping in your stores. This week in #stalker sightings: Jimmy Fallon, Susan Sarandon, Michael C. Hall, and LaToya Jackson.

Blue Tulip Rose Read is definitely not stalking BBC Radio DJ Mike Read. Sure, she had her name changed to his and prints his picture on t-shirts and shows up at his work—that's love, not stalking!

Last Friday, New York Times restaurant critic Sam Sifton wrote that he would be eating at KFC today. So naturally, Eater "posted operatives at every branch of KFC in Manhattan." And caught Sifton in the act! Scared yet, media people?

A tipster tells us this photo was taken about 1:30 this afternoon on Madison Avenue. There is financial guesser Jim Cramer, just standing out on Madison Ave., typing financial data things on his computer. Really? Crazy, if true!

Rielle Hunter has some artistic differences with the photographer who shot her sexy photos for GQ. But she is apparently a fan of this new exhibit at the Guggenheim. Today a reader spotted her and John Edwards there getting cultured.

In Leaves of Grass Edward Norton plays twins, one of whom deals pot. At last night's snack-accompanied SxSW screening, Edward's mellow went up in smoke when he thought he received a bill for his munchies. A witness writes in.

Spotted at 28th Street and Park Avenue last night: Actor Liev Schreiber hopping out of his car to chat with the NYPD after an apparent ding with a truck. A citizen paparazzo hid behind a scaffold and snapped a pic.

Every day in New York City, celebrities are sweating on the treadmill next to you at the gym and taking up tables at restaurants. Lately in #stalker sightings: Richard Gere, Alan Cumming, Lady Gaga, and Mischa Barton.

Yes, they were all at the West Chelsea club last night, and our tipster got all the dirt. Snooki is tiny, The Situation wears velvet, DJ Paulie Dashing is charming, and Sammi and Ronnie are still together!

While you ate lunch, celebrities roamed the Earth. Today in #stalker sightings: Jude Law and Sienna Miller (twice!) and John Slattery.

Gawker's spies are everywhere. And here's a rundown of today's posts on the #stalker page: You saw Stacy London, Ed Westwick, one of the Olsens, Blake Lively and Rhea Perlman.

December 14th: Lance Bass at Kiss & Fly Sunday to celebrate Malik So Chic's bday. He was flirting with a half-naked waiter, who turned out to be straight. (Plus: a reminder on the new ways to submit Stalker sightings)

We get some decent Stalker Sightings on the weekends, even with our spies hard at work brunching and shopping and, really, probably reporting these drunk. Yet some are especially concise, astute, catty, or somehow otherwise spectacular. Like this one.

A tipster just spent her entire lunch hour eavesdropping on SUV-driving PR menace Lizzie Grubman and Elle magazine PR honcho (and The City star) Erin Kaplan at Meatpacking restaurant Pastis. Too bad the tip was a fake.

Stalked: Sonia Sotomayor at Po on Smith Street. Someone spot her at Bar Great Harry!

Oct. 22 @ 11:15 am Glee's Sue Sylvester was in a corner at Clinton Street Bakery Co. laughing and eating pancakes with friends. No track or zoot suits. Post your own Gawker Stalker sightings or send them to stalker@gawker.com

Oct. 18 @ 1pm At the Northface store on W. 73nd and Broadway. He stood around while she shopped and then he paid for her items. [Post your own Gawker Stalker sightings or send them to stalker@gawker.com]

Oct. 14 @ 12:55pm Making out with some chick right outside the Council on Foreign Relations. She was pretty, but ordinary girl pretty. Not hot, not his typical slampiece. [Submit your own Gawker Stalker sightings to stalker@gawker.com]
