不自然なガール / ナチュラルに恋して by Perfume

"Fushizen na Girl/Natural ni Koishite" (不自然なガール/ナチュラルに恋して, Fushizen na Gāru/Nachuraru ni Koishite) is Perfume's first 2010 single and tenth major single release. It was released on April 14, 2010 as a CD-only version and CD+DVD version. The single was notable for being Perfume's second double A-side after Baby Cruising Love / Macaroni. As such, two promotional music videos were shot. "Natural ni koishite" was used in a tie-in promotion with Japanese clothing line Natural Beauty Basic. A music critic Haruo Chikada points out in his music column "考えるヒット"(Kangaeru Hitto Considering hits) the antonymy of the two titles and compares the sound of Natural ni Koishite to Scritti Politti.
