Wish I could have been there, love to all."\r\n\r\nThe news of this get-together comes shortly after Newton-John opened up about her struggles to stay positive amid her cancer battle. In an interview with Entertainment Tonight, she says, "I just want everyone to know, I'm here, I'm doing great. I'm doing really well and I'm really healthy. It was a challenging year because I broke my sacrum and I had to learn to walk again and everything. But I am strong and I am back and I'm feeling good and loving every minute."\r\nNewton-John has been through the wringer with cancer before\r\n\r\n\r\nNewton-John first battled cancer in 1982 and underwent a partial mastectomy in addition to reconstruction surgery. She then receives a diagnosis a second time in 2013 and a third in 2018. She was admitted to her own facility, the Olivia Newton-John Cancer Wellness & Research Center in Australia, and stayed there for three weeks.\r\n\r\nIt\u2019s now been reported that\u00a0the star plans to raise even more money by donating her own valuables, including parts of her\u00a0Grease\u00a0wardrobe. This includes the stunning leather jacket she sported at the end of the film and the matching leggings. They had been put away in her closet for the last 40 years!\r\n\r\n\r\n\r\nAdditionally, Newton-John opens up about how her cancer diagnosis has been for her mentally on Australian TV's\u00a0Sunday Night.\u00a0She says, "When you're given a cancer diagnosis or a scary illness diagnosis, you are suddenly given a possibility of a time limit. If you believe the statistics, you're going to make them happen. If somebody tells you, 'you have six months to live', very possibly you will - because you believe that."\r\n\r\nShe definitely does a fantastic job at staying positive and hopeful despite everything! We are sure that the surprise get-together from her friends helps, too.\r\n\r\n\r\n\r\nWe are praying for you, Olivia!\r\nThe actress has been open about her use of medical cannabis during her cancer battle, learn more here!
