�� Diamonds are a Girl's Best Friend! Based on Anita Loos’s 1925 bestseller of the same title and later adapted to the legendary Marilyn Monroe film, this iconic musical follows the glamorous and diamond-digging Lorelei Lee, a blonde from Little Rock, Arkansas, who sails to Paris with her fun-lovin' best friend Dorothy Shaw. En route, the girls meet a number of accommodating gentlemen, one who loses his diamond Tiara to Lorelei, and another who loses his heart to Dorothy.
