Tatiana Boncompagni Hoover is a socialite married to a vacuum-cleaner heir, and likes to play up her tenuous ties to Italian royalty. She just wrote a thinly-veiled novel about life in the upper strata of Manhattan called Gilding Lily. Her sister, Natasha Boncompagni, has chick-lit aspirations as well. FIGHT! As Page Six reported yesterday, the sisters are in court—Natasha told us that Tatiana installed a "remote keylogging device" on her computer, which she says Tatiana used to steal the manuscript and copyright herself as the co-author of the upcoming Hedge Fund Wives. Tatiana says that Natasha stole it from her computer and that she's the sole author. Who's sort-of winning?Tatiana, so far: "A federal judge yesterday issued a temporary restraining order against former Wall Street gal Natasha Boncompagni, forbidding her from staking claim to the soon-to-be-published Hedge Fund Wives," Page Six reported. But: "Given my sister's motto 'No publicity is Bad Publicity,' I wouldn't be surprised if she isn't pleased with all the attention," Natasha told us, later pointing to Patrick McMullan photos of Tatiana at the Dylan's Candy Bar party last night, "basking in the attention." Ladies, ladies. You can both wear high heels! Let's not let a feud deprive readers of this sure-to-be remarkable work of post-colonial fiction.
