Uma buys a River House co-op; Rihanna rents a Chinatown loft; Chloe Sevigny heads to Brooklyn; Joy Behar stays put on the Upper West Side.

After getting past a notoriously tough co-op board (Diane Keaton and Gloria Vanderbilt weren’t so lucky), Uma Thurman recently purchased a $10 million co-op at the venerable River House at 435 East 52nd Street for herself and her three children. Raising the celebrity factor even more, the 13-room apartment belonged to popular novelist Barbara Taylor Bradford and her filmmaker husband, who are reportedly apartment-hunting on Park Avenue (NYPost).

Rihanna is adding pop star cachet to Chinatown by choosing a duplex penthouse in a loft conversion there. The sultry singer will be renting an apartment at 129 Lafayette Street (pictured) – it was on the market in April for $14.66 million – for $39,000 a month. The four-bedroom condo loft rocks a 2,400-square-foot wraparound terrace with Lower Manhattan views, a media room and a bar (TRD).

Former East Village It Girl Chloe Sevigny recently purchased a very grown-up “classic six” in an elegant full-service Park Slope co-op at 9 Prospect Park West, also home to NY Sen. Charles Schumer. The apartment was recently on the market for $1.75 million. The indie film actress – and Big Love star – recently sold her East Village garden apartment for $1.76 million (CurbedNY).

Comedienne and TV talk show host (The View) has sold her sunny two-bedroom co-op at Astor Court at 205 West 89th Street for $1.9 million, just above the $1.79 million ask. The apartment’s 10-foot-ceilings and wood-burning fireplace were likely reasons it was only on the market for a few weeks before finding a buyer. The NYC native won’t be leaving the neighborhood or even the building – she has another apartment just a few floors up (NYO).

A recent Vanity Fair video features Jackie O’s famous residence at 1040 Fifth Avenue (Onassis purchased her 15th floor apartment in 1964), also home to National Enquirer founder Gene Pope; the two public figures lived peacefully as neighbors though they traveled in vastly different – and sometimes conflicting – circles (Vanity Fair).
