Actress Jane Seymour has recalled her final visit to close friend Olivia Newton-John before her death.
The former Bond actress, who had known the Grease star since 1976, told Good Morning Britain: "She hung in there a really long time and she was in so much pain. Those of us who knew her at the end, we didn't want her to go but, at the same time, it wasn’t a life for her any more.
"I remember when she first had the back problem because she called me from Vegas when she was performing. She said, 'Jane, what do I do? My back is hurting’. Who knew that that was actually cancer in her spine, which was devastating.
"But John (Easterling, her husband) has always been incredible and really helped her through it. He is an expert in herbs and all kinds of alternative medicines as well. She lived in peace.
"The last time I sat there was at the back and she didn’t know I was coming. She got the day wrong. Somehow she got in some sort of clothes and came out and she just kept looking around and she said, ‘Look at those hummingbirds, look at the sky, look at nature. Isn’t it beautiful?’ That’s who she was. She just grabbed every moment."
Sharing a picture of the pair together, Peter Andre hailed her as "a true icon" who was "warm, kind and caring to everyone".
