Well as far as I know she was Ringo's companion around '75-'77. I don't know what brought her into his life or what made them split up.
She looked like a pretty, willowy brunette, not much "chest power" if you know what I mean. She even shared a composing credit w/ Ringo - the (horrendous) track "Las Brisas" from "Ringo's Rotogravure".
She appeared on several snapshots by his side during that time, even when Ringo had all his facial hair cut off (even his eyebrows !), when he was suffering from some kind of intestinal ailment.
