LAS VEGAS, April 23 (UPI) -- Australian pop star Olivia Newton-John says she has postponed her planned Las Vegas residency because her sister Rona was diagnosed with brain cancer.
Olivia Newton-John, 64, is a breast cancer survivor.
"I received the very sad news that my beautiful sister, Rona Newton-John, has been diagnosed with brain cancer. In light of this news, I have decided to postpone my forthcoming Las Vegas residency to spend time with her and our family," Newton-John said in a statement to the Las Vegas Sun.
