Shoe king Stuart Weitzman walked into a room full of familiar faces at the Empire Hotel Lobby Bar when family and friends threw him a surprise 70th birthday soiree Tuesday night. Guests were all holding up oval paper fans in front of their faces that displayed a picture of the birthday boy’s face on one side, while the opposite side read, “Stuart’s Surprise Seventieth Soiree.” Naturally, the cake was in the shape of a Stuart Weitzman shoe box adorned by a mini pingpong table with the paddles and ball, as the designer is a fan of the game.
