getting the wrong idea ??

Do you know "mihimaru GT"?? mihimaru GT is unit which consist of 2 person (hiroko and miyake ) . I like their song, my favorite song is "気分上々↑↑". I've heard this song in a CM which is hair coloring meterial ("Palty" from DARIYA Corporation) . When I saw this CM, I thought that a girl is not hiroko. I thought she is Mari Yaguchi from ex-Morining Musume. What do you think this get tingthe wrong idea??
