Who is this girl ? (Context in the post)

Left, the boy is Goro Noguchi, an idol mostly popular in the 70s. But at right ? I can see the name “Jeana” written but I have done some research and did not find any informations any her. Does anybody know who she is ?

I do not have the source of the photo (I think I took it from a site who sells this type of magazine).

By the way, if anybody knows any teenagers/young adult foreigners who were popular in Japan in the 70s please let me know, I don’t know why but I have such a niche interest in them lol (examples : Björn Andresen, René Simard, maybe Olivia Hussey, Renault Verley, etc.)
