NOW: Olivia Newton-John
Now 65, Newton-John is rarely seen on the big or small screens in the United States, but she continues to tour around the world performing her music. Last year, Olivia teamed up with her friend and "Grease" costar John Travolta for the holiday album "This Christmas," which benefited The Olivia Newton-John Cancer & Wellness Centre and the Jett Travolta Foundation. —XFINITY Entertainment Staff (Photo: Scott Barbour/Getty)
