The feud between Tatiana and Natasha Boncompagni rages on. As you may recall, Tatiana is the author of the chick lit novel Gilding Lily and the forthcoming book Hedge Fund Wives; Natasha, her sister, claims she co-authored Hedge Fund Wives and says the book is based on her career on Wall Street. Earlier this week, Tatiana filed suit against Natasha, claiming her sister had stolen a copy of the manuscript and posted it online. Natasha countered her sister's claim with the assertion that Tatiana had tried to pay her to go away and had lied to her publisher, HarperCollins, on numerous occasions, most notably about being the daughter of an Italian princess. (She also said her sister had installed a "keylogging" device on her computer so she could spy on her.) Yesterday a judge issued a temporary restraining order forcing Natasha to take down the site that had previously hosted several sections of the novel. But Tatiana's already-battered reputation is about to take another blow. It turns out that she's not even named "Boncompagni" and her vacuum heir husband had a very similar legal run-in of his own not so long ago.

Tatiana and Natasha both graduated Edina High School in Edina, Minnesota where, one of their former classmates tells us, neither woman went by the name "Boncompagni." Both were known by the name Schneiderman—the last name of their father—and it wasn't until they both became adults that they started using "Boncompagni," their mother's maiden name. By the time Tatiana had morphed into a fixture on the New York social scene (and started bragging about those $1,000 haircuts), she'd changed her name legally as well as picked up the fanciful tale that her mother is an Italian princess.

As for Tatiana's husband, Max Hoover, he certainly won't be a stranger to Judge Laura Taylor Swain if he appears by his wife's side in court. In 2006, a longtime business partner of Hoover's named Chris Kosachuk sued him for defrauding him and denying him profits from the company they started together, Good Energy. (The lawsuit is here.) The lawsuit was later dropped after the parties reached an out-of-court settlement, although Kosachuk's claims are suspiciously similar to those made by Natasha Boncompagni against Tatiana.

We called HarperCollins to ask them about the author they've been billing in PR materials as an "Italian princess." We'll let you know when we hear back.
