If you happen to be interested in the current whereabouts of New York's most famous former prostitute (and the city's newest sex columnist), a tipster tells us that Ashley Dupre is getting her hair cut right now at the Warren-Tricomi salon in Midtown. You're welcome.

Is Tiger Woods hiding out at the Long Island mansion of Jim Dolan, the "controversy-prone CEO of Cablevision and owner of Madison Square Garden and the New York Knicks"? That's what Us Weekly reported this morning, although reps for Dolan have called the story "preposterous." [Us]

The first batch of homeless Chihuahuas will be arriving in New York from Los Angeles today. (As you may recall, Paris Hilton's fascination with the breed a few years back led a big bunch of California residents to adopt Chihuahuas, but many of them were abandoned when the fad passed.) As part of "Operation Chichuahua Airlift," about 15 dogs will be landing at JFK today aboard a Virgin America flight. Why NYC? According to the ASPCA, "the East Coast has long had a shortage of small dogs." [AP, ABC News, previously]

• Back in July, word spread that financially troubled movie producer Vittorio Cecchi Gori's 52nd-floor apartment at the Trump International—a 5,500-square-foot pad that Donald Trump himself once owned—had gone into contract for $18 million, making it "possibly the largest residential foreclosure action ever in Manhattan," according to the Times. It's been six months since then, but the gutted palace in the sky is now back on the market. The penthouse, which will undoubtedly require many millions to whip into shape—or is "a complete blank canvas" in the words of Prudential Douglas Elliman managing director Howard Margolis—can now be yours for $28.5 million.

Raj Rajaratnam, the hedge fund billionaire (and dwarf enthusiast) accused of insider trading, has even more legal trouble on his hands today. Prosecutors say they plan to tack on another bunch of charges to their original indictment, a move that could increase Rajaratnam's prison sentence to 15 years (or more) if he's ultimately convicted. Even more concerning: The Wall Street Journal unveiled a new illustration (or "hedcut") of Raj in the paper today, and his smile and casual, open-collared look has been replaced with one that makes him look much more defendant-y. That can't be a good sign, can it? [NYT, Dealbreaker, previously]

• An autopsy has been performed on Casey Johnson, the socialite and pharma heiress who was discovered dead on Monday. There weren't any signs of trauma, but more should be revealed when toxicology tests are completed. In the meantime, friends of Johnson report she went into a diabetic coma on several occasions over the past year, "spent the last months of her life in a suicidal drug haze," and had been living in squalor up until her death, since her family had cut her off. Speaking of the Johnson clan, they're planning to have a private funeral for Casey later this week. [TMZ, NYP, NYDN, People]
• In other Johnson news, she was dealing with a long list of legal problems when she died, including a lawsuit by Porsche (for failing to keep up with her car payments), and another suit by a nanny service (which claimed it was owed money). As for fame addict Tila Tequila, her alleged fiancée, she's been busy posting to Twitter, recounting the "haunting visions" she's been having of Johnson and how they "made such a lovely couple."

Manhattan federal judge Jed Rakoff has been nicknamed "Judge Dread" on Wall Street for his efforts to hold banks and financial execs accountable for their actions. (He's currently overseeing the case against Bank of America, which is accused of misleading investors regarding bonus payouts, and he's also presiding over the trial of Raj Rajaratnam, the hedgie charged with insider trading.) So how does Rakoff blow off steam when he isn't taking on big banks and crooked execs? He engages in a little ballroom dancing, that's what. [BusinessInsider]

So much for that report about Marc Jacobs getting married to fiancé Lorenzo Martone on St. Barts earlier this week. A rep for the designer says it was just an engagement party (albeit one that happened to involve the presence of a wedding cake). [Us, The Cut, previously]

Renting a room at Manhattan Mini-Storage could easily run you $100 a month. A far cheaper solution: Buy a junky used car, fill it up with all the crap you own (and should really throw out), and then park the car on the street for free!

Hedge fund manager David Tepper is a rare breed. Not only did he earn $2.5 billion in 2009 while many of his peers just struggled to keep their heads above water, he still lives in the same New Jersey home he and his wife have occupied since 1990, he's yet to buy a vacation home, and he still sends his kids to public school. [BN]

And now for some news that will totally shock you: According to a new survey, Americans are more unsatisfied with their jobs than ever. [NYDN]

Marc Jacobs and Lorenzo Martone were supposed to get married in Provincetown this past summer. They never ended up going through with it for whatever reason, although that may have changed over New Year's vacation. According to the fashion blog Styleexperts, the couple tied the knot in a private ceremony on St. Barts earlier this week, an event that was hosted by art dealer Larry Gagosian and which featured a cake topped with an edible Jacobs (sans shirt), Martone (dressed in a tux), and two of their dogs.
