Before settling down with model Behati Prinsloo, singer Adam Levine resided in a chic Hollywood Hills home decorated by Mark Haddawy and outfitted with classics by 20th-century-design icons. The living room is a well-edited haven of vintage pieces: a Dunbar sofa in Maharam mohair velvet, a Stilnovo floor lamp, a Jean Prouvé cocktail table, a Hans J. Wegner Ox chair, and a Ludwig Mies van der Rohe daybed. The pillows are covered in antique Caucasian textiles, and the carpet is 1920s Persian.
