Olivia Newton-John Pulls Out of Las Vegas Residency After Sister Is Diagnosed with Brain Cancer

Gregory Pace/FilmMagicPop legend Olivia Newton-John is postponing a planned Las Vegas residency to spend time with her older sister, Rona Newton-John, who has been diagnosed with brain cancer.  The 64-year-old Grease star, who beat breast cancer 20 years ago, has issued an official statement revealing that she recently received "the very sad news" of her 69-year-old sibling's diagnosis.

"In light of this news, I have decided to postpone my forthcoming Las Vegas residency to spend time with her and our family," writes Olivia.  "As a cancer 'thriver' myself, as many people are, I am very aware of the importance of love, support and family during this journey she is about to begin."

The Las Vegas Sun recently reported that the Australian singer was about to announce details of the gig, which was set to start this summer at the Flamingo hotel.  Newton-John would have alternated dates with Donny and Marie Osmond, who have an ongoing residency at the venue.  According to the Las Vegas Sun, Olivia is expected to reschedule the residency eventually.

Rona Newton-John also was an actress, and was married to Olivia's late Grease co-star Jeff Conaway from 1980 to 1985.
