• Madonna fell off a horse while riding at photographer Steven Klein's house in Bridgehampton on Saturday. She wasn't seriously injured, but don't think for a minute she's taking any blame for the spill. Her flack blamed the accident on a rogue paparazzo who jumped out of the bushes and startled the horse, although both the photographer in question and the police don't share that account.

We've received three sightings of magician/fake stuntman David Blaine today, and all seem legit. Here's the best one: "5pm: Walking East on 11th b/w 5th & University talking on his cell phone insisting 'No, you have to tell them that I'm not going to perform that!'" Heh.

The magical Anderson Cooper agrees: David Blaine is a scrub. [CNN]

Yesterday we (and others) pointed out that "magician" David Blaine is a big fat cheater, because his current death-defying stunt—hanging upside-down in Central Park for 60 hours—involves hourly ten-minute breaks. As one commenter put it, "I'm going to eat a thousand hard-boiled eggs, but I'm only going to eat one a day for a thousand days, because otherwise I might get sick." Yes, that about sums it up. Blaine's flack said there was never any claim he would hang for 60 consecutive hours. Really? You couldn't tell that from his fawning media coverage: Today, the half-ass nature of Blaine's stunt is being pointed out across the UK, in India, and domestically. But did America's prestigious media outlets bother to point out the very germane fact of Blaine's hourly breaks when they initially reported on his stunt? Let's see: The AP (no mention of breaks):

More info, photos, and a statement from David Blaine's flack have been added to our earlier post about Blaine's cheating ways.

Is David Blaine a big cheater or what? The droopy-eyed "magician" is currently engaged in his latest stunt, hanging upside down for 60 hours in Central Park. Except that ever since he started yesterday afternoon, we've been getting emails from bystanders saying that he wasn't hanging upside down—instead, he was resting by standing on a platform, only to be hoisted up several minutes later. We don't know the official explanation, but whatever it is, this sure is a crappy stunt. Here's photographic evidence:
6:45 p.m. yesterday:

Drew Barrymore walking in the West Village ... Alex Rodriguez leaving a workout at the Reebok Gym ... Spike Lee posing for photos outside a hotel ... Julianne Moore carrying a shopping bag ... Kelly Ripa and David Blaine hanging upside down in Central Park for a Live segment ... Blake Lively and Leighton Meester walking around the Gossip Girl set ... Real Housewives' Alex McCord posing on the red carpet at the Metropolitan Opera season opener ... Actor Mark Ruffalo holding hands with his wife as they cross the street ... Natasha Bedingfield and Caroline Rhea leaving ABC Studios in Midtown ... and Chris Rock and Lance Armstrong outside the David Letterman show.

Today on Live With Regis and Kelly, pint-sized Kelly Ripa strapped herself into a harness and ventured skywards to awkwardly join illusionist David Blaine in the midst of his latest attention-whoring stunt: hanging upside down for three days in New York's Central Park. He stopped eating a week ago so he won't have to go to the bathroom and is using a catheter, plus, he's been warned the feat may leave him blind. Fun! But nay, fear is not a factor for Blaine - who told Ripa he's only scared of beatles and spiders. Ripa, on the other hand, had her greatest fear realized while vocalizing it: "looking like a basset hound on TV." [Live With Regis & Kelly]

Katie Holmes on stage for the opening night of her play and then leaving dinner with Tom Cruise afterward ... and David Blaine and Donald Trump announcing Blaine's next stunt inside Trump Tower.

• Jennifer Lopez competed in a triathalon in Malibu, then flew to New York to throw Marc Anthony a birthday party at the Bowery Hotel. It's unclear, though, if she ever had an injured foot, which was the reason she gave for pulling out of the Project Runway finale last week and now some are wondering if a fight with Harvey Weinstein over a movie role was the real reason she cancelled. [People, NYDN, MSNBC]

• Two waitresses at 1Oak say they were fired from Scott Sartiano's club so that they could be replaced with white girls. Now they have a lawsuit in the works. [P6]

We have a feeling that, were there a group of deadbeat dads out in Glendale (a la those Dina Lohan-lovin' freaks out East) who got drunk enough one day to form a Totally Awesome Dads Association (TADA!), they would most likely celebrate their first-year anniversary by handing out their Bud Light-drenched award for Father Of The Year to Papa Joe Simpson. Why? Well, as we already know, the former minister-turned-dadager managed to pimp out a few mind-numbingly boring exclusive wedding pictures featuring most annoyingly faux-punk new marrieds on the planet, Ashlee Simpson and Pete Wentz, to People a few weeks back. But what we didn’t know was that, at the same time, Simpson was allegedly attempting to sell off his other daughter Jessica — not to the tabloids, but to then-boyfriend Tony Romo. See the astonishing managing skills this guy has? But he reportedly wasn’t stopping at selling off his daughter — he was also said to be pressuring the quarterback to sign a client/manager agreement and become one of the magically successful Simpson Family Players:
