Aby Rosen had a terrific birthday party last night thrown by his wife, Samantha, and Tico Mugrabi at the new Paramount Hotel. The decor, designed by Bronson van Wyck, was fabulous! There was a photo booth, plus ballet dancers hanging from the celling. The energy was great — so many people were dancing! To name everyone there would fill up two blogs, but some were Vera Wang, Mary-Kate and Ashley Oslen, Jen Creel, Emily Smith, Debbie Peltz, Bono and Nicky Hilton.
