The Hollywood star Kelly Preston, who was married to former Grease star John Travolta, tragically passed away last August at the age of 57 after a private battle with breast cancer. Travolta’s former Grease costar Olivia Newton-John, who is currently battling breast cancer herself, spoke out this week to pay tribute to Preston.

“Kelly was a lovely, beautiful woman, both inside and out,” Newton-John, 72, told Fox News. “She had a very sweet, gentle spirit. And we shared care for the environment. We made a video together when her baby was born and when [my daughter] Chloe was a young baby. We made a video at our home for the Children’s Health Environmental Coalition about pesticides and things that you have under your sink that can be dangerous for children.”

“Kelly and I were the hosts of that video,” Newton-John added. “And we went to Washington together also to change legislation with Nancy and Jim Chuda, who started the foundation. So that was my very special time with Kelly. I saw her over the years, but she was a beautiful person.”

Newton-John is currently battling cancer for the fourth time, but she recently let fans know that she is “feeling great.”

“I’m so lucky to still be doing all these things,” Newton-John told People Magazine. “I don’t think I imagined living this long! I feel very blessed.”

Newton-John recently teamed up with her 39 year-old daughter Chloe Lattanzi to release a duet and music video titled, “Window in the Wall,”

“I just hope that it affects people the way it affected me,” Newton-John said. “I mean, this song was sent to me by a woman that I’ve only met a few times, and she sent it to me saying, ‘I really believe you need to record this song.’ I was very doubtful but the feeling that I got, I felt emotional and I felt it was really an important song.”

“I wasn’t planning on singing at all,” she added. “But when I heard the lyrics about how we have forgotten how to love, I mean, there’s such tension on the planet and the lyrics are so profound about how we should be respecting other people’s opinions even if we don’t agree with them.”

In the end, Newton-John is hoping that 2021 will bring “love and forgiveness in all things that we do.”

“I think we have forgotten that a bit,” she said. ‘I think that this time on the planet has separated us, which is really a shame.”
