We can't get enough of the kids of Manhattan's quasi-famous residents. They're so attractive and sexy and just legal enough to vamp for the hipster photo sites. Today it's Isabelle McNally, the daughter of Balthazar and Pastis mastermind Keith McNally. It's unconfirmed, but as an aspiring actress (who isn't?), we hear that Isabelle's had trouble at a few prestigious schools because of her nasty habits, but according to her MySpace she's now a proud member of Narcotics Anonymous. Too bad — she looked like she might be kind of fun! And we sure could use a half-naked, troubled bad-girl heiress skanking around Last Night's Party, just to mix things up a bit.
