A silver-clad Anne Hathaway sparkled at a recent Sutton Tower penthouse cocktail party celebrating Bulgari’s partnership with Save the Children, we hear.

Bulgari’s 16-year partnership with the non-profit has helped more than 2.4 million children, according to reports.

Hathaway — whose homes with husband Adam Shulman include a West Coast Swiss chalet hideaway once owned by Yves Saint Laurent and Wes Anderson — looked right at home in the stunning duplex, which asks a cool $65 million.

At 9,191 square feet, the posh penthouse comes with five bedrooms and 6.5 baths. It’s all inside the Upper East Side’s tallest tower.

The residence opens directly from a private elevator into an entry gallery that leads to a great room with 15-foot high ceilings, a fireplace and city views.

There’s a chef’s kitchen, a formal dining room, a butler’s pantry and a bedroom on the first floor. Design details include a striking, 166-square-foot double-height loggia and a staircase that leads to four bedrooms upstairs, which all come with ensuite baths.

The second floor also offers a media room, a sitting room and a laundry room. The main bedroom suite boasts tons of closet space, and two ensuite spa-like baths. 

The 850-foot tower, at 430 E. 58th St, was designed by architect Thomas Juul Hansen, who also created the interiors. It was completed just last year.
