Now Seymour remembers her BFF for her exuberant personality and giant heart.

Seymour’s father, an obstetrician-gynecologist in Britain, delivered Rona’s child and Newton-John’s nephew, Emerson.

“She sings,” Seymour remembered her dad saying.

“She has a sister in America who sings too.”

Her bond with Newton-John began when Seymour told her friend she was pregnant.

She remembered the “Xanadu” actor asking “How can you do it all?”

Regarding their 40-plus-year friendship, Seymour and Newton-John certainly did it all for each other.

“We were like confidants to one another.”
