Grace Hightower, who is the wife of actor Robert De Niro, has gone to contract to sell her 25th-floor, 1,653-square-foot unit in the Trump Palace building on Manhattan's Upper East Side after it had been listed for $2,495,000, according to the New York Post.

Hightower had owned the unit since 2000, according to public records. She purchased it for an undisclosed price after De Niro filed for divorce from her 1999. The couple reconciled in 2003, and most recently, Hightower and De Niro paid $20.9 million in October 2006, according to public records, to buy a 15-room duplex co-op unit on the fourth and fifth floors of the Brentmore building at 88 Central Park West on Manhattan's Upper West Side from Eve Weinstein, who is entertainment mogul Harvey Weinstein's ex-wife.

Now, Hightower has unloaded her estrangement pad in the Trump Palace, which is at 200 E. 69th Street. Features in the three-bedroom convertible unit include three baths, city views, a living room with a balcony, a galley kitchen, a windowed dining room, and a master bedroom with a marble Jacuzzi tub and a separate stall shower, a double sink, a large customized walk-in closet and an alcove sitting area, according to listing information. Other features include a second bedroom with an en suite marble bath and custom built-ins, according to listing information. The New York Post's fine celebrity real estate columnist Braden Keil broke the story last week of Hightower's sale, and the Real Estalker followed it up with some nice coverage as well.
