Ballet patrons celebrate in one of the grandest apartments on the UES: PHOTOS

Dancers and the people who support them held a celebration at the Upper East Side home of Susan Gutfreund on Friday night.

The event was for the Youth American Grand Prix, which helps young dancers around the world realize their potential. Before the party, guests enjoyed a performance of “Jewels” at Lincoln Center, where the Paris Opera Ballet, New York City Ballet and Bolshoi Ballet each performed one act.

Notable guests of the event included Amy Astley, Barbara and Gary Brandt, Amy Fine Collins, Joanna Fisher, Olivia Flatto, Judith Hoffman, Allegra Kent, Kristina Allegra Kingston, Regina Kudoyarova, Lillian Kraemer, Margot London, Tara Milne, Vicki Reiss, Ralph Rucci, Denise and Andrew Saul, Denise Sobel, George Vanderploeg, David Weinreb and YAGP Board Chair Linda K. Morse with her husband, Ed.

Gutfreund’s is not just any Upper East Side apartment; until recently, it was the most expensive listing in the city, asking $96 million. According to StreetEasy, it is no longer listed.
