Introducing CityRealty's latest New York Insider Column: Notable Neighbors

New Yorkers are totally not celebrity-obsessed. Movie stars. Yawn. Julia Roberts at the playground with her kids, Conan at the hardware store, Bon Jovi jogging; we're used to it! Yet our famous neighbors validate our choice to live in this crazy town: People who could live anywhere they wanted choose to live here, too.

In case you hadn't heard: SJP plus eight...bedrooms? Gaga turns restaurateur, the Godfather house hits the market, Courtney Love loses out and Kelsey Grammer buys into a vision machine.

Everyone's got an opinion about Sarah Jessica Parker and Matthew Broderick's alleged acquisition of a $21-plus million dollar triplex at 88 Central Park West (via The New York Observer). The saga of their search has been as much about what they passed over (54 Bond, 610 Park Avenue) as it was about which big-ticket address finally won out.

Lady Gaga is getting back to her roots with a recent investment in an Upper West Side Italian restaurant, Vince & Eddie’s. The over-the-top performer has fond memories of the low-key neighborhood establishment, and her parents (who are also investors) are still regulars (via HuffPo).

Frasier star Kelsey Grammer has reportedly bought himself a cog in Jean Nouvel's “Vision Machine,” also known as 100 Eleventh Avenue (via CurbedNY). The six-and-a-half mil apartment in the metal-and-glass West Chelsea condo will give the boyish middle-aged star plenty of room to escape the demands of an unhappy estranged wife (Beverly Hills Real Housewife Camille) and new squeeze Kayte Walsh.

The Corleone mansion from The Godfather is up for sale. The Staten Island manse where the 1972 mobster masterpiece was filmed is going for $2.9 million, and the “offer you can't refuse” joke has already been made (via A/V Club).

Courtney Love lost out on the chance to move her doll parts into Milla Jovovich's townhouse at 100 Greenwich Ave (she was outbid by IMAX chief exec Rich Gelfond), but Courtney watchers are vigilant (via CurbedNY).
