He also performed a live dance routine with Jennifer Lopez.

Cruise’s portrayal of Grossman was a surprising, borderline incomprehensible comedy turn for the actor a few years ago in Tropic Thunder, and his return on MTV for the opening of the show was equally a surprise. He was helped in the opening sketch by some of the biggest young stars today – Robert Pattinson, Taylor Lautner and Jaden Smith (along with Cruise’s buddy Will Smith) as he introduced the show that was to come. Or, as Grossman put it as only he can: “I’m going to shove this lump of coal up my ass, clench my buttcheeks and crap out a diamond for you, the viewer.”

But it wasn’t just the pre-taped opening – Cruise showed up to ‘rescue’ the show from a silly Ed Helms musical number, and on the urging of Ludacris, performed his famous dance from Tropic Thunder. Then J Lo showed up and they danced together. Was it a totally head-scratching pairing? Sure, but it was also a moment that will be remembered for awhile (or at least become part of the next MTV special about their awards shows).

Side note: how many of the Twilight-loving tweens making up the majority of the audience knew it was Tom Cruise? Check out Grossman’s opening and performance below:

Also, our Thanksgiving day marathon of top movie and TV Thanksgiving moments, which you can alternately choose to watch whilst stuck in a plane, train, or automobile or, when you need a break from being asked to explain to family members what exactly it is you write about on the Internet all day long. Fortunately! Some of these movies are available in their entirety on YouTube…meaning someone had their family Thanksgiving cap on. Anyway, enjoy it now, enjoy it later and if you have suggestions feel free to leave in the comments and we will do our best to add. In the meantime, have a safe Getaway Day and a Happy Thanksgiving.

Let me ask you, what kind of person do you think Scarlett Johansson is?

You have probably never met her, and I definitely have not, yet we both seemingly feel like we could describe her personality with reasonable accuracy.

This is peculiar.

It’s not shocking to learn that humans enjoy making personality judgments based upon scant evidence. But with celebrities it seems exceptionally dubious, since we actually know literally nothing about them first-hand. Lohan, Aniston, Springsteen, Cruise — why do all these people seem to have well-formed personas? How much of it is real and how much is manufactured? What are the sources we use to scrape together these mysterious portraits?

There are a few known mythological origins. Maybe that profile in Rolling Stone had some lasting influence, and perhaps those eight minutes on Leno left an impression. But these sources, mediated and filtered and manicured, seem exceptionally unreliable. So what else is there?

Oh yeah, we have their work. Scarlett gave a lasting impression in Lost in Translation, so perhaps we know a little more about her because of how she gobbles sushi with Bill Murray. But wait — she was acting. Can we really conclude anything about her personality from these flickering screen moments?

I’ve spent an inordinate amount of time considering this question: why do we think we know people who we’ll never actually know?

Here’s my best guess: we trust gossip.

Before mass media, gossip was merely personal information shared about a mutual acquaintance. In other words, pre-modern gossip was the original conversational marketing: valued information shared by reputable sources.

With the onset of broadcasting, publishing, and eventually the internet, the intimacy of gossip bred with the entertainment industry, birthing the hybrid offspring known was celebrity gossip. Of all the animals in the media zoo, celebrity gossip emerged as the most chimerical creature. Every day, hundreds of weird little stories pop up on sites with names like Hollywood Tuna and Egotastic and Celebrity Puke. Sometimes they make outrageous claims (Amy Winehouse just ate a drunk baby!), and other times the narratives are ostentatiously mundane (Tara Reid just ate a taco!). Through these morsels of checkout lane anti-matter, we form lasting opinions about celebrities.

That finally brings us to today’s launch of GossipCop.com, a site that I did the strategy/design/development on. The premise is simple: investigate the accuracy of the daily anecdotes, the rampant rumors, and the cubicle grist known as celebrity gossip. Think of it as TMZ meets Smoking Gun. Or maybe Perez Hilton meets Columbia Journalism Review. Whatever — the prevailing idea is that even seemingly unknowable information can be investigated in today’s info-rich economy.

My three favorite features on the site:

+ Truth Meter. Every post investigates a piece of celebrity gossip and provides a rating, from 0 to 10, based upon the likelihood of the story.

+ Paparazzi Patrol. Rather than churn out more celebrity video, Gossip Cop looks at the underside of the celebrity gossip business. By turning the camera back on the paparazzi, the site reveals the gossip creators for what they are. (This feature was originally dubbed “Papsmeared,” a name I really loved but which was ultimately dropped.)

+ Twit Happens. With its direct interaction and unfiltered access, Twitter could end up being the greatest invention in celebrity journalism since the camera. It is quickly become the ultimate device for determining how impressions are made, rumors are debunked, and celebrity battles are fought. This hand-picked list contains the best tweets of the day.

Truthfully, I’m not much of a celebrity news consumer. But I hope this site adds a new angle into the salacious, rumor-driven celebrity culture.

And maybe I can finally get to know Scarlett.
